Research Summary:
The Eid group research is in the areas of nano-fabrication and spintronics. We use electron beam lithography and photolithography extensively to fabricate the needed nano-scale devices. After that we measure their spin-dependent resistance (magnetoresistance) at cryogenic temperatures down to about 7K in external magnetic fields.
Our lab houses a class 1000 cleanroom facility and a magnetic characterization lab. The construction of the lab is being completed in July 2008.
Most our nano- and micro-devices are based on the ferromagnetic semiconductor GaMnAs. Being both a ferromagnet and a semiconductor at the same time, GaMnAs devices can have added flexibility and rich science compared to other semiconductor nano-devices.
One of the recent research projects in the group is to fabricate lateral nanostructures of metal/GaMnAs and study their tunneling magnetoresistance (TMR) in detail. We are also working on fabricating “tunable magnetoresistance” nano-devices that will potentially enable the gate control of the magnetoresistance effect.
