AuGe-Ni-Au based Ohmic Contacts to GaAs Structures
T. S, Abhilash / Rajaram, Guruswamy
This book presents the magnetic, electrical and surface morphological characterization of AuGe/Ni/Au Ohmic contact metallization on GaAs/AlGaAs two-dimensional electron gas (2DEG) multilayer structures. These structures, have well known applications in infrared sources/detectors, high-speed electronic devices (HEMTs) and high sensitivity Hall effect magnetic field sensors. Deposition of AuGe/Ni/Au followed by rapid thermal anneal is a well tes...
