TTU Physics Department.

Condensed Matter Physics

Overview

The theoretical condensed matter group at TTU consists of three faculty members, Prof. Estreicher, Prof. Myles, and Prof. Sanati. The group is active in two main areas: crystalline semiconductors and metallic alloys. We combine theoretical and computational methods to investigate the mechanical, optical, electrical, and thermal properties of materials.

The experimental condensed matter group at TTU consists of three faculty members. Prof. Lichti's main research effort uses MuSR (muon spin rotation, relaxation, or resonance) methods to investigate the defect properties of hydrogen impurities in semiconductor materials using the short-lived muonium 'isotope' of H. A second direction for these investigations uses implanted positive muons as a sensitive probe of the atomic scale magnetic fields within various magnetic semiconductor materials being developed for possible spintronics applications. Prof. Kaye's current research interests concern optical properties of semiconductors, phase-changing materials, and the ability to transition science into useful and deployable tools. Prof. Grave de Peralta's research in NTC concentrates on Fourier and ultra fast optics, plasmonics and mechanical properties of light. In addition, he is interested in the fundaments of Quantum Mechanics (Quantum Optics).

NTC is a conglomerate of laboratories facilities. NTC projects include researchers, graduate, and undergraduate students from Electrical, Computer, Chemical, and Mechanical Engineering, Physics, Computer Science, Biology, Chemistry, and Medicine. Research is supported by numerous Federal, State, and Industrial grants. The Center supports new education programs in MEMS, Silicon Processing, and Semiconductor Product Engineering.
