Title [sv]
Effektiv energiomvandling med extrema material
Title [en]
Efficient power conversion with extreme materials
Abstract [sv]
Projektet avser att tillverka heterostrukturer för kraftelektronik (dvs kombinationer av olika material) baserade på de tre halvledarmaterialen galliumnitrid (GaN), aluminiumnitrid (AlN) och diamant (C). Kraftelektronik baserad på material med extrema bandgap förväntas både att minska förluster och minska eldistributionssystemens totala kostnader på grund av dessa materials förmåga att fungera vid högre spänningar än kisel- och kiselkarbid-baserad teknologi.
Abstract [en]
The aim of this project is to make power electronic devices for high voltages with extremely low losses. Certain semiconductor materials with extreme bandgaps have marvellous charge transport properties and high breakdown voltage, which makes these ideal for high-voltage high power device applications. Carbon (synthetic diamond films) in particular has ideal properties, and combines these properties with a very high thermal conductivity. However, introducing free charges by doping is a problem in diamond. Therefore, in order to solve this problem, we propose to theoretically and experimentally investigate heterostructures with other doped extreme bandgap semiconductors, such as aluminium nitride and gallium nitride. The goals are: 1. To establish charge injection and transport properties across GaN/C and AlN/C heterojunctions. 2. To perform an extensive device simulation study for optimization of heterojunction devices. 3. To demonstrate devices based on heterostructures.
