UV Detector based on InAlN/GaN-on-Si HEMT Stack with Photo-to-Dark Current Ratio > 107
Sandeep Kumar, Anamika Singh Pratiyush, Surani Bin Dolmanan +3
We demonstrate an InAlN/GaN-on-Si HEMT based UV detector with photo to dark current ratio > 107. Ti/Al/Ni/Au metal stack was evaporated and rapid thermal annealed for Ohmic contact…

Dielectric Engineering of HfO2 Gate Stacks Towards Normally-ON and Normally-OFF GaN HEMTs on Silicon
Hareesh Chandrasekar, Sandeep Kumar, K. L. Ganapathi +9
We report on the interfacial electronic properties of HfO2 gate dielectrics both, with GaN towards normally-OFF recessed HEMT architectures and the AlGaN barrier for normally-ON Al…
