Low Resistance Non-Alloyed Ohmic Contacts to High Al Composition n-type AlGaN
Joseph E. Dill, Xianzhi Wei, Changkai Yu +6
Ohmic contacts to high (>70\%) Al content n-type AlGaN ultra-wide bandgap semiconductor layers in nitride electronic and photonic devices are typically fabricated by a…
Quantum oscillations of holes in GaN
Chuan F. C. Chang, Joseph E. Dill, Zexuan Zhang +12
GaN has emerged to be a major semiconductor akin to silicon due to its revolutionary impacts in solid state lighting, critically enabled by p-type doping, and high-performance radi…
Two-Carrier Model-Fitting of Hall Effect in Semiconductors with Dual-Band Occupation: A Case Study in GaN Two-Dimensional Hole Gas
Joseph E. Dill, Chuan F. C. Chang, Debdeep Jena +1
We develop a two-carrier Hall effect model fitting algorithm to analyze temperature-dependent magnetotransport measurements of a high-density ( cm/Vs) polar…
Ultrawide bandgap semiconductor heterojunction p-n diodes with distributed polarization doped p-type AlGaN layers on bulk AlN substrates
Shivali Agrawal, Len van Deurzen, Jimy Encomendero +7
Ultrawide bandgap heterojunction p-n diodes with polarization-induced AlGaN p-type layers are demonstrated using plasma-assisted molecular beam epitaxy on bulk AlN substrates. Curr…
