Walter M. Klahold

Walter M. Klahold is a Part-Time Lecturer in the Department of Physics & Astronomy at the University of Pittsburgh, affiliated with the Dietrich School of Arts and Sciences. His research focuses on semiconductor materials, particularly silicon carbide (4H-SiC), and its applications in harsh-environment electronics.

• Education:
  • Master of Science (MS) in Physics
  • Doctor of Philosophy (PhD) in Physics

Research Interests:
Dr. Klahold's work investigates the energy level structure of free excitons in 4H silicon carbide using advanced techniques like wavelength modulated absorption (WMA) spectroscopy and low-temperature photoluminescence. His studies focus on resolving previously unobserved free exciton ground-state splittings and analyzing avoided crossings in valence bands, contributing to understanding the electronic band structure of SiC.

Academic Contributions:
His dissertation, "Energy Level Structure of Free Excitons in 4H SiC from Wavelength Modulated Absorption Spectroscopy and Low Temperature Photoluminescence," highlights his research on semiconductor physics and optical properties of SiC. He has collaborated with advisors Wolfgang J. Choyke and Robert P. Devaty on high-resolution spectroscopic analyses.
