Research Description

Professor Jaszczak's research focuses on theory and computer modeling of materials. His current work focuses on single-electron transistor devices, in collaboration with the experimental groups of Dr. Y. K. Yap (Physics) and Dr. Paul Bergstrom (Electrical and Computer Engineering). He also studies materials in which interfaces, such as surfaces, grain boundaries, or interphase boundaries, play an important role. He uses a collection of simulation methods including Monte Carlo and molecular dynamics, as well as numerical and analytical techniques.

Dr. Jaszczak also has interests in the elastic properties of superlattices, phase transitions at surfaces, crystal shapes, crystal growth, and nanotechnology education.

  • Theoretical condensed matter physics
  • Theory and modeling of single-electron transport devices
  • Modeling and simulation of properties of interfaces and interface materials
  • Atomistic computational physics of surface phases and surface dynamics
