"Our researches focus on two parts: 1. novel growth technique of SiGe molecular beam epitaxy (SiGe MBE) and 2. fundamental optical and electrical properties of functional SiGe material and devices. For the first part, we have developed modulated impurity doping in low-temperature Si buffer layer and ultra low-temperature Si buffer layer. By these growth methods, we fabricate the functional SiGe devices, such as superlattices, quantum wells, quantum dots and photodetector and photoemitter in THz regime. For the second part, we measure the properties of devices mentioned above in the high magnetic field at the low temperature, such as magneto-luminescence effects, quantum hall effects and so on. Our labs are located at room B115 and B114b in the CCMS building. "

Quantum Devices Laboratory is directed by Prof. Ming-Hua Mao. Current research focuses on two major areas: (1) Fabrication and application of quantum-dot devices.

The lowest threshold current of 0.45 mA is achieved at room temperature from a device of 6.5 μm in diameter with single-mode emission. These microdisk lasers with superior properties can be applied in miniaturized photonic devices, energy-saving or intergration with Si waveguide structures for optical interconnec
