GERMANIUM-BASED PHOTODETECTOR WITH REDUCED DARK CURRENT AND METHODS OF MAKING THE SAME
A photodetector including a substrate having a semiconductor material layer, such as a silicon-containing layer, and a germanium-based well embedded in the semiconductor material layer, where a gap is located between a lateral side surface of the germanium-based well and the surrounding semiconductor material layer. The gap between the lateral side surface of the germanium-based well and the surrounding semiconductor material layer may reduce the surface contact area between the germanium-containing material of the well and the surrounding semiconductor material, which may be a silicon-based material. The formation of the gap located between a lateral side surface of the germanium-based well and the surrounding semiconductor material layer may help minimize the formation of crystal defects, such as slips, in the germanium-based well, and thereby reduce the dark current and improve photodetector performance.
