معرفی
Joseph H Ngai is an Associate Professor in the Department of Physics at the University of Texas at Arlington. His research focuses on complex transition-metal oxide thin films and heterostructures, grown via oxide molecular beam epitaxy (MBE), integrated with semiconductors. He has held academic positions since 2012, including postdoctoral training at Yale University.
Ngai earned his PhD in Physics from the University of Toronto (2007), following MS (2002) and BS (2001) degrees from the University of Toronto and University of Alberta, respectively.
Research Interests: His work explores novel functionality in oxide heterostructures, including nanoscale mechanical properties of ferroelectrics, band-gap engineering at semiconductor-oxide interfaces, and device prototyping for energy and information technologies. His custom-built MBE system enables precise epitaxial growth on both oxides and semiconductors.
Publications & Grants: Ngai has published extensively in journals like Physical Review B, Nano Letters, and Journal of Applied Physics, focusing on epitaxial growth, interface dynamics, and device applications. He leads federal and state-funded projects, including NSF grants exploring ferroelectric functionality and oxide-semiconductor integration.
Advising & Teaching: He has advised over 20 graduate and undergraduate students, focusing on materials science and physics. Teaches courses on Solid State Physics, Thermodynamics, and oversees research through directed studies (PHYS 4325, 4315, and dissertation advising).
Labs & Collaborations: His research group collaborates with institutions like Northwestern University (NSF partnership) and AFRL, focusing on GeSn epitaxy and functional oxide integration. His lab emphasizes interdisciplinary approaches to materials innovation.
