Ohmic contacts optimisation for High-Power InGaAs/AlAs double-barrier resonant tunnelling diodes based on a dual-exposure e-beam lithography approach
(Universiti Malaysia Perlis (UniMAP), 2021-12)In this paper, we report on a simple test structure which can be used to accurately extract the specific contact resistivity ρc associated with metal-n++ InGaAs-based low-resistance Ohmic contacts through the transfer ... -
The role of selective pattern etching to improve the Ohmic contact resistance and device performance of AlGaN/GaN HEMTs
(Universiti Malaysia Perlis (UniMAP), 2021-12)In this work, we report the processing and DC performance of fabricated AlGaN/GaN HEMT devices using 3 different patterned Ohmic contact structures. The types of Ohmic contact patterns used are horizontal, vertical and ...
