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).
