Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

InfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

Nanoengineered silicon/silicon dioxide nanoparticle heterostructures

Solid State Sciences, 2005
Abstract Engineering control of nanostructures is becoming increasingly important as nanotechnology applications develop and as device features shrink. In many nanotechnology-driven applications, bottoms-up fabrication of devices offers many inherent advantages over conventional top-down approaches typically employed today.
