Spontaneous Synchronization for Cooperative Light Emission
Brief description: The project’s focus is to investigate how two-level systems synchronize light emission spontaneously at the nanoscale. The project has both theoretical and experimental dimensions: modeling of cooperative interactions (e.g., dipole-dipole, field-dipole coupling) with relevance to adjacent phenomena of amplified spontaneous emission and lasing; experimental studies of nanocrystal assemblies exhibiting collective emission, as well as macroscopic LED prototypes.

Enzymatic reaction enabled by photo-electro catalysis
In this project, you will work with our novel nanowire electrode for light-induced water splitting and catalytic reactions. We are using this electrode to regenerate NAD+ to NADH. NADH is the co-factor used in 1/4 of all enzymatic reactions. In this project we study the regeneration reaction using light as one of the driving components. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale and thus see a clear pathway for later industrialization.

Simulation of matter-light interaction in porous nanowire-based Photo-electrode with world record quantum efficiency
In this project, you will work with our novel nanowire electrode for light-induced water splitting. In this electrode based on silicon nanowires coated with a plasmonic layer, we have found plasmonic and light-guiding effects that significantly influence the optical absorption. In initial Finite-Difference Time-Domain (FDTD) calculations, we could reproduce the effects such as diameter, length coating. This work now needs to be expanded to include more complicated structures that will allow us to precisely tune the optical absorption. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale.

Using Atomic layer deposition to create a passivation layer on porous nanowire-based Photo-electrode with world record quantum efficiency
In this project, you will work with our novel nanowire electrode for light-induced water splitting. In this electrode based on silicon nanowires coated with a plasmonic layer we have found plasmonic and light-guiding effects that significantly influence optical absorption. Essential for the functioning of these electrodes is their longevity. To reach industrial-relevant periods, we need to extend our current lifetime by developing and depositing a novel passivation layer using atomic layer deposition at the NanoLund facilities. You will develop this layer and use state of the art analysis methods at e.g. MaxIV to characterize it. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale.

Studying light-matter interactions in porous nanowire based Photo-electrode with world record quantum efficiency using action spectroscopy
In this project, you will work with our novel nanowire electrode for light-induced water splitting. In this electrode based on silicon nanowires coated with plasmonic layer we have found plasmonic and light-guiding effects that significantly influence optical absorption. Based on Finite-Difference Time-Domain (FDTD) calculations and experiments, we can in principle, tune the optical absorption of silicon nanowires by adjusting their shape. In this work, we want to explore this effect to create nanowires that absorb specific wavelengths in the infrared. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale.

Studying the efficiency of photocatalysis in porous nanowire based Photo-electrode using in-situ Raman Spectroscopy
In this project, you will work with our novel nanowire electrode for light-induced water splitting. In this electrode based on silicon nanowires coated with plasmonic layer we have found plasmonic and light-guiding effects that significantly influence optical absorption. The electrode we are creating is highly efficient in creating e.g. hydrogen. However to further improve the efficiency it is essential that we can characterize the produced gases in-situ, meaning during operation. For that you will design a setup in which we can perform Raman spectroscopy in the headspace (the place above the electrodes) to determine the hydrogen concentration without disturbing the reaction below. This will include building a resonator setup and to write the analysis software. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale.

Using polymeric self assembly for creating pattern in nanowire synthesis
In this project, you will work with our novel nanowire electrode for light-induced water splitting. Our electrodes are synthesized from a metallic pattern on stock silicon wafers. Currently these seeds are created with a lithograhic step that we aim to replace. Polymers in the right blend can self-assemble to form distinct patterns on a surface. These patterns can then be transferred into a metallic mask. The advantage of using this polymeric approach is the free scalability of the sample. Or with other words it is essential for making wafers large enough for industrial deployment. What makes this project unique is that we currently have a remarkable quantum efficiency of 13.3% solar to hydrogen conversion efficiency in a system that can effectively be created even on a larger scale.

Describing light induced dynamics with probabilistic methods
Over the last 15 years we have developed a modelling software for kinetic modelling of dynamical processes called KiMoPack. We have currently approx. 200 users worldwide. The current library of kinetic models is based on differential equations that describe the different flows. In this project we want to describe kinetic models using probabilistic methods, which is essential for any dynamics in solids. We also want to create a GUI to select and effectively fit these models and interface with the currently develop AI version of tool. This project requires basic Python knowledge.

Develop the Next generation of detectors for Material Analysis
We are excited to offer a master thesis opportunity in Physics, Electrical Engineering, or Chemistry to develop a new type of detector for X-ray fluorescence using semiconductor nanowires. We are aiming to build a new generation of x-ray detectors based on a new design of nano-wires. Originally developed for infrared spectroscopy, our innovative material system utilizes the complex electronic surfaces of nanowires to produce a very high optical gain, i.e. many charge carriers for a single absorbed x-ray photon. This high gain increases both the sensitivity and spectral resolution that can be achieved with a detector. This promising development has wide-reaching applications in various industries, such as analyzing color pigments in images, detecting contaminations in food, and metal analysis. As a master student, you will build a small light-tight chamber with a pre-amplifier and potentially an AD converter based on Arduino, and then test the nanowire detectors with a tabletop X-ray source or the cutting-edge synchrotron radiation facility, MaxIV. With our pre-tests showing that this type of detector works in principle, the main objective will be to perform more careful tests and build a prototype to evaluate its real performance. The ideal candidate should have some experience with microelectronics and be excited about working independently on this project for 3-6 months. This is an excellent opportunity to make a significant contribution to scientific advancement and potentially develop a product with a wide reach. Join us in this exciting journey to push the boundaries of modern detection technology!

Using the phenomenon of luminescence for optical calculations
Here we are using the concept of memlumor and the memory effects observed in photoluminescence response of semiconductors (in particular in metal-halide perovskites). We are searching for innovative optical schemes which would combine classical optical computing in free space (e.g. Fourie filtering) with the possibility to have memory in the luminescence signal. Potentially this can enable neuromorphic optical calculations on these novel principles.
