A complex optical model potential correlated by the conception of bonded atom, which considers the overlapping effect of electron clouds between the two atoms i
Very deep zero-order metallic grating structures are processed to study the transmission properties of THz radiation pulses. The experiments have been performed
We report the fabrication of an upconversion infrared detector, i.e. a quantum well infrared photodetector integrated with a light-emitting diode (named as QWIP
A novel lateral double-gate tunnelling field effect transistor (DG-TFET) is studied and its performance is presented by a two-dimensional device simulation with
The output intensity variations of the laser used in a prism coupling system are observed and found to be induced by the exteal optical feedback, which comes fr
