Germanane and (3-Hydroxypropyl)germanane as Single Crystal Photodetectors

Popis výsledku v původním jazyce

2D materials are being widely investigated for their potential application in light-detecting devices. Very recently, a spin-coated flexible 2D germanium-based photodetector with great photocurrent density and responsivity as well as short rise and decay time is presented by Liu et. al. In this paper, the solid-state single flake photodetector base on either pure germanane or (3-hydroxypropyl)germanane is reported. Both prepared photodetectors while irradiated with different wavelengths of light exhibit outstanding responsivity of 1157 mA W−1 for GeH and 362 mA W−1 for (3-hydroxypropyl)germanane, which exceeds Liu&apos;s flexible reported GeH photodetector (22 µA W−1) by more than five orders of magnitude. These constructed photodetectors also exhibit rise and fall times lower than 20 ms, which is also significantly faster than the GeH photodetector reported by Liu with rise and decay times 240 and 740 ms, respectively.
