Main Focus
The increase in heat production via the electrical current limits a further increase of signal velocity and miniaturization of semiconductor devices. There is no heat production in the ideal case of pure spin currents in magnetic semiconductors. We focus on the fabrication of diluted magnetic semiconductors by means of pulsed laser deposition or by magnetic ion implantation and short time annealing and on the manipulation and detection of spin currents in semiconductor spintronics devices with new functionalities.
Another approach towards the reduction of heat production is the use of the highly non-linear dynamic response of memristors to support both logic and memory simultaneously.
Materials Under Study
Semiconductor nanostructures (InAs/GaAs, Ge/Si), magnetic semiconductors (ZnO:(Mn,Co), In2O3:(Mn,Cr), GaAs:Mn, Ge:Mn, GaN:(Mn,Co)), novel spintronics devices (Tunnel magnetoresistance structure, Spin field effect transistor), memoxide nanostructures (VO2, BiFeO3).
