Low resistance ohmic contacts to n-GaAs for application in GaAs/AlGaAs quantum cascade lasers
ohmic contacts sputtering
2011/5/10
This paper reports on the results of optimization of ohmic contacts for GaAs/AlGaAs quantum cascade lasers (QCLs). Technological parameters during optimization concerned surface preparation, evaporat...
Investigation on microstructure evolution of oxidized Ni/Au ohmic contacts to p-GaN by XRD
microstructure evolution Ni/Au p-GaN XRD
2010/7/15
The microstructure evolution of oxidized Ni (20nm)/Au (20nm) contact to p-GaN with increasing annealing temperature was studied by synchrotron x-ray diffraction (XRD) and powder XRD. With the increase...
