Research Interests:

Experimental Condensed Matter The research of Professor Jiang's group is centered on exploring new phenomena of low-dimensional semiconductor systems. One area of the research is to study the quantum phase transitions in a variety of two-dimensional charged systems in the quantized magnetic fields, so-called the quantum Hall systems. Ongoing experiments include magneto-transport and photo-luminance probes of electron delocalization and magnetic phase transitions in an electron system with two interacting subbands, and thermodynamic measurements of the unexpected zero-field metal-insulator transition in a highly correlated 2D hole system. Another research area is to develop a fundamental building block for quantum computation and quantum information processing in advanced semiconductor heterostructures, called spin-resonance-transistors. Electrical and optical measurements are done regularly in Jiang's laboratory for temperature down to 50 mK and magnetic field up to 15 T. Fabrication facilities including an electron-beam lithography system are also available for the fabrication of sub-micron scale semiconductor structures. Experiments are also performed at the National High Magnetic Field Laboratory at Florida, and at the Los Alamos National Laboratory.
