4 MV/cm (010) $β$ -Ga $_{2}$ O $_{3}$ Heterojunction Diodes Realized by Low-Damage e-Beam NiO $_{x}$ Interlayers

Carl Peterson, Yizheng Liu, Chinmoy Nath Saha +3

We report on the utilization of a low-damage e-beam NiO $_{x}$ deposition process to realize field-plated heterojunction diodes (FP-HJDs) on (010) $β$ -Ga $_{2}$ O $_{3}$ films with high crit…

Realization of Insulating Buffer Layers via MOCVD-Grown Nitrogen-Doped (010) \b{eta}-Ga2O3

Rachel Kahler, Carl Peterson, Sriram Krishnamoorthy

We present MOCVD-grown, nitrogen-doped \b{eta}-Ga2O3 films as an insulating buffer layer on Fe-doped (010) \b{eta}-Ga2O3 substrates in lieu of 49% HF treatment to remove unintentio…

Kilovolt-Class $β - G a_{2} O_{3}$ Field-Plated Schottky Barrier Diodes with MOCVD-Grown Intentionally $1 0^{15}$ $c m^{- 3}$ Doped Drift Layers

Carl Peterson, Chinmoy Nath Saha, Rachel Kahler +4

We report on the growth optimization of intentionally low-doped ( $1 0^{15}$ $c m^{- 3}$ ) high-quality $β - G a_{2} O_{3}$ drift layers up to 10 $μ m$ thick via MOCVD and the fabrication of kil…

Record-High Electron Mobility and Controlled Low 10 $^{15}$ cm $^{- 3}$ Si-doping in (010) $β$ -Ga $_{2}$ O $_{3}$ Epitaxial Drift Layers

Carl Peterson, Arkka Bhattacharyya, Kittamet Chanchaiworawit +7

We report on metalorganic chemical vapor deposition (MOCVD) growth of controllably Si-doped 4.5 $μ$ m thick $β$ -Ga $_{2}$ O $_{3}$ films with electron concentrations in the 10 $^{15}$ cm$^{…
