N-type doping of LPCVD-grown \b{eta}-Ga2O3 thin films using solid-source germanium
Praneeth Ranga, Arkka Bhattacharyya, Luisa Whittaker-Brooks +2
We report on the growth and characterization of Ge-doped \b{eta}-Ga2O3 thin films using a solid germanium source. \b{eta}-Ga2O3 thin films were grown using a low-pressure chemical…
Defect states and their electric field-enhanced electron thermal emission in heavily Zr-doped beta-Ga2O3 crystals
Rujun Sun, Yu Kee Ooi, Arkka Bhattacharyya +4
Performing deep level transient spectroscopy (DLTS) on Schottky diodes, we investigated defect levels below the conduction band minima (Ec) in Czochralski (CZ) grown unintentionall…
The anisotropic quasi-static permittivity of single-crystal beta-Ga2O3
Prashanth Gopalan, Sean Knight, Ashish Chanana +11
The quasi-static anisotropic permittivity parameters of electrically insulating gallium oxide (beta-Ga2O3) were determined by terahertz spectroscopy. Polarization-resolved frequenc…
Impurity Band Conduction in Si-doped \b{eta}-Ga2O3 Films
Anil Kumar Rajapitamahuni, Laxman Raju Thoutam, Praneeth Ranga +2
By combining temperature-dependent resistivity and Hall effect measurements, we investigate donor state energy in Si-doped \b{eta}-Ga2O3 films grown using metal-organic vapor phase…
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…
Highly tunable polarization-engineered two-dimensional electron gas in -AlGaO3 / -Ga2O3 heterostructures
Praneeth Ranga, Sung Beom Cho, Rohan Mishra +1
We report on the modeling of polarization-induced two-dimensional electron gas (2DEG) formation at -AlGaO3 / -Ga2O3 heterointerface and the effect of spontaneous polarization…
