The quality of the interface, e.g., the semiconductor–semiconductor or metal–semiconductor interface, is the main factor restricting the photodetection performance of a heterojunction. In this study, a high‐quality Se/Si interface is constructed via in situ directional transformation of amorphous Se (a‐Se) into crystalline Se (t‐Se) on a Si substrate via light annealing. Benefitting from the high‐quality...
Attitude Estimation is critical for autonomous flight of aircraft. In this paper, an attitude estimation method for Miniature Unmanned Helicopter (MUH) is presented. The method is based on Unscented Kalman Filter (UKF). It employs Quaternion to represent rotary motion. It utilizes information from three low-cost single-axis MEMS gyroscopes, two dual-axis accelerometers and a three-axis electronic...
