Research Interests

Dr. Liu’s research interests are:

  • Structural, electrical, and optical properties of semiconductor alloys and their heterotructures.
  • Band structure, optical, electrical and magnetic properties of diluted magnetic semiconductors, including bulk and low-dimensional structures.
  • Growth by molecular beam epitaxy of low-dimensional semiconductor structures.
  • Physics of low-dimensional systems.
  • Physics of ferromagnetic semiconductors.
  • Electrical transport in magnetic semiconductors.
  • Electronic spin phenomena in semiconductor nanostructures.
  • Semiconductor/superconductor hybrid structures (e.g., such as the submicron-patterned superconductor-diluted magnetic semiconductor bi-layers).
