RADICON applies chemical thermodynamics to semiconductor physics to discover novel bottom-up fabrication routes for p-n-heterojunctions, enabling ground-breaking innovations within energy conversion, here optoelectronics, photocatalysis, and electrochemistry. The project explores the novel concepts by theory, properties, fabrication, and applications by a range of methodologies from ab initio calculations and semiconductor physics to in situ electrical and electrochemical characterisation, utilising UiO's state of the art laboratories in semiconductor physics and solid-state electrochemistry as well as national infrastructures. The project runs through to early demonstration in a phase 1 pre-project, and a deeper study and optimisation for efficiency in a main phase 2. Various routes for further research and exploitation are planned for the different directions of applications, pending positive results, IPR, and publication. The project is a collaboration between Department of Chemistry and Department of Physics at University of Oslo within the Centre for Materials Science and Nanotechnology (SMN). At the beginning of the demonstration phase, a screening has been done for materials with proper alignment of electronic states at the interface of the two materials, which determines how electric charges can be transferred across it to warrant high device performance. In the next step, both top-down and bottom-up fabrication methods are being explored to make junctions for electrical and electro-optic characterization. Current-rectifying properties have been found on one of the novel materials pairs, establishing a first step towards the project?s first objective.

RADICON applies chemical thermodynamics to semiconductor physics to discover novel bottom-up and fabrication routes for p-n-heterojunctions. This leads in consequence to a range of ground-breaking innovations within energy conversion, here optoelectronics, photocatalysis, and electrochemistry. The project explores the theory, properties, fabrication, and applications by a range of methodologies from ab initio calculations and semiconductor physics via atomic resolution microscopy and spectroscopy to in situ electrical and electrochemical characterisation, utilising UiO's state of the art laboratories in semiconductor physics and solid-state electrochemistry as well as national infrastructures. The project runs through to early demonstration in a phase 1 pre-project, and a deeper study and optimisation for efficiency in a main phase 2. Various routes for further research and exploitation are planned for the different directions of applications, pending positive results, IPR, and publication. The project is a collaboration between Department of Chemistry and Department of Physics at University of Oslo within the Centre for Materials Science and Nanotechnology (SMN). It runs for 1+2 years, recruits and trains 2 researchers, and integrates 3 MSc projects.
