TL;DR: The generality of the above results suggests that the present monolayer graphene/germanium IR photodetector would have great potential for future optoelectronic device applications.

TL;DR: Finite element method (FEM) simulation results show that this novel nanostructure array/MLG heterojunction can trap UV photons effectively within the ZnONRs and suggest that this MLG film/ZnONR array Schottky junction UVPD will have potential application in future optoelectronic devices.

TL;DR: A silicon nanowire array/carbon quantum dot core-shell heterojunction photovoltaic device by directly coating Ag-assisted chemical-etched SiNW arrays with CQDs that could function as a high-performance self-driven visible light photodetector operating in a wide switching wavelength with good stability, high sensitivity, and fast response speed.

TL;DR: In this article, the shape evolution process and the formation mechanism of CuS nanotubes as well as the thermal stability of these materials were studied, and the results demonstrated that suitable sulfur sources such as thiourea and thiacetamide which release ionic sulfur rather than molecular sulfur at their decomposition temperature are favorable for the formation of these material, in contrast to sulfur powders.

TL;DR: In this article, a self-driven near infrared light photodetector (NIRPD) was proposed for NIR light detection, which showed an obvious rectifying behavior with a turn-on voltage of 0.6 V.
