Microwave Irradiation Assisted Deposition of Ga2O3 on III-nitrides for deep-UV opto-electronics
Piyush Jaiswal, Usman Ul Muazzam, Anamika Singh Pratiyush +5
We report on the deposition of gallium oxide using microwave irradiation technique on III nitride epi layers. We also report on the first demonstration of a gallium oxide device, a…
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…
High Responsivity in Molecular Beam Epitaxy (MBE) grown \b{eta}-Ga2O3 Metal Semiconductor Metal (MSM) Solar Blind Deep-UV Photodetector
Anamika Singh Pratiyush, Sriram Krishnamoorthy, Swanand Vishnu Solanke +4
In this report, we demonstrate high spectral responsivity (SR) in MBE grown epitaxial \b{eta}-Ga2O3-based solar blind MSM photodetectors (PD). (-2 0 1)-oriented \b{eta}-Ga2O3 thin…
