Facilities and Resources

(Ultra)Wide Bandgap Semiconductor Research Laboratory

Our laboratory is located at UMass Lowell North campus, Ball Hall 308. We combine dedicated in-lab tools with shared university and partner facilities that support materials growth, microscopy and spectroscopy, nanofabrication, electrical testing, and radiation exposure studies.

Materials Growth

Low-Pressure Chemical Vapor Deposition (LPCVD)

Epitaxial growth of Ga₂O₃ and related oxides, including doped films and process exploration for scalable, high-quality layers.

Halide Vapor Phase Epitaxy (HVPE)

HVPE growth facility for thick, low-doped Ga₂O₃ drift layers for vertical device development.

Radiation Laboratory

The UMass Lowell Radiation Laboratory houses a 1 MW swimming-pool–type nuclear research reactor and a 5.5 MV Pulsed Van de Graaff accelerator capable of generating proton, deuteron, alpha-particle, or oxygen-ion beams in pulsed or dc mode. These facilities support work on neutron and gamma detectors, radiation-resilient electronics, non-destructive testing, and the study of radiation-induced material modifications.
