Oxygen annealing induced changes in defects within beta-Ga2O3 epitaxial films measured using photoluminescence
Rujun Sun, Yu Kee Ooi, Praneeth Ranga +3
In this work, we use photoluminescence spectroscopy (PL) to monitor changes in the UV, UV', blue, and green emission bands from n-type (010) Ga2O3 films grown by metalorganic vapor…
Low Temperature Homoepitaxy Of (010) -GaO By Metalorganic Vapor Phase Epitaxy : Expanding The Growth Window
Arkka Bhattacharyya, Praneeth Ranga, Saurav Roy +3
In this work, we report on the growth of high-mobility -GaO homoepitaxial thin films grown at a temperature much lower than the conventional growth temperature window fo…
Analytical Modeling and Design of Gallium Oxide Schottky Barrier Diodes Beyond Unipolar Figure of Merit Using High-k Dielectric Superjunction Structures
Saurav Roy, Arkka Bhattacharyya, Sriram Krishnamoorthy
This work presents the design of beta-Ga2O3 schottky barrier diode using high-k dielectric superjunction to significantly enhance the breakdown voltage vs on-resistance trade-off b…
Degenerate doping in \b{eta}-Ga2O3 Single Crystals through Hf-doping
Muad Saleh, Joel B. Varley, Jani Jesenovec +4
N type conductivity of \b{eta}-Ga2O3 grown from the melt is typically achieved using Sn and Si. In this paper, we experimentally and computationally investigate Hf doping of \b{eta…
Schottky Barrier Height Engineering In -GaO Using SiO Interlayer Dielectric
Arkka Bhattacharyya, Praneeth Ranga, Muad Saleh +4
This paper reports on the modulation of Schottky barrier heights (SBH) on three different orientations of -GaO by insertion of an ultra-thin SiO dielectric interlaye…
Delta-doped \b{eta}-Ga2O3 thin films and \b{eta}-(Al0.26Ga0.74)2O3/\b{eta}-Ga2O3 heterostructures grown by metalorganic vapor-phase epitaxy
Praneeth Ranga, Arkka Bhattacharyya, Ashwin Rishinaramangalam +4
We report on silicon delta doping of metalorganic vapor-phase epitaxy-grown \b{eta}-Ga2O3 thin films using silane precursor. Delta-doped \b{eta}-Ga2O3 epitaxial films are character…
