Photoresponse Enhancement in Ge MSM Photodetector With Ge Micropillar Array

Improving detection efficiency of Ge photodetector near the absorptance edge is crucial for fiber-optic telecommunication. Here, we report the unique photodetection properties of germanium (Ge) metal-semiconductor-metal (MSM) photodetector with Ge micropillar array. The responsivity and detectivity...
