YIA-CHUNG CHANG
Research Specialties
Developing novel theoretical methods for investigating electronic, optical, and transport properties of semiconductors and low-dimensional systems such as quantum wells, nanostructures and two-dimensional materials. Exploring intriguing physical phenomena related to excitons interacting with surrounding free carriers from the strongly correlated phase (in low density) to the Fermi-liquid phase (in high density). Exciton condensation, magnetic multilayers and giant magnetoresistance, AC Stark phenomena, photonic crystals and cavities, optical metrology of semiconductor thin films, gratings and nano/microstructures, infrared and radiation detectors, semiconductor lasers and modulators, resonant tunneling diodes, quantum transport properties, single-photon generators, spintronics, nanophotonics, and biosensing via plasmonic nanostructures.
