Alejandro Perez
PhD Student
Alejandro’s research focuses on the design, fabrication, and characterization of N-Polar GaN HEMTs (High Electron Mobility Transistors). Gallium Nitride based devices have surfaced as a candidate for high power and RF applications due to their unique properties. In N-polar devices, the two-dimensional electron gas (2DEG) is formed on top the AlGaN barrier. This unique property allows better confinement of the 2DEG and better gate control. These devices also allow us to achieve smaller dispersion, in addition to other benefits which leads to better overall performance. The fabrication process includes physical and chemical vapor deposition, optical and electron-beam lithography, dry and wet etching, and atomic layer deposition, etc. Additionally, he hopes to achieve device optimization using Silvaco ATLAS device simulations.

Rockwell Dax
PhD Student
Rockwell’s research is primarily based on exploring the theory, characteristics, and applications of 2D semiconductor materials. Specifically, his work focuses on developing Transition Metal Dichalcogenides (TMDCs) and other 2D materials into viable semiconductor alternatives to the existing photon-based or trapped-ion physical implementations of qubits within the realm of quantum computing. Additionally, he aims to improve device performance and physical viability in existing applications through experimental and theoretical study.

Chia-Heng Sun
PhD Student
Chia-Heng’s research focuses on exploring the mechanisms of Schottky barrier formation in 2D semiconductor-metal interfaces. By using DFT analyzing the interface states and interface dipoles, we can better understand the nature of Fermi-level pinning in TMDC (such as MoS2)-metal contacts and further improve the contact performance.

Toan Phan
PhD Student
Toan’s research is concentrated on investigating the design and fabrication process of GaN-based metal-insulator-semiconductor heterojunction field effect transistors (MISHFETs) to optimize performance under high-frequency operations. His fabrication process includes physical and chemical vapor deposition, optical and electron-beam lithography, dry and wet etching, and atomic layer deposition. Some other systems of interest include Au-free, low RTA temperature ohmic contacts on AlGaN/Gan heterojunctions and enhancement-mode AlGaN/GaN MISHFETs.
