TL;DR: For the first time, a bi-directional (positive and negative) photoresponse is demonstrated at different wavelengths, due to the opposite charge transfer direction of the photoexcited carriers enforced by the unique band alignment.

TL;DR: Surprisingly, it was found that the Bi2Te3/pentacene heterojunction photodetector exhibited a fast and wideband response from 450 to 3500 nm, which indicates that the inorganic/organic heteroj junction, that is, the combination of 3D TIs with organic materials, is an exciting structure for high performancePhotodetectors in the wideband detection region.

TL;DR: In this article, a wide-band photodetector based on heterojunction of Cd3As2 thin film and pentacene for the first time was demonstrated, which can detect the radiation wavelength from 450 nm to 10600 nm at room temperature.

TL;DR: This paper demonstrates a graphene/C 60 /pentacene vertical phototransistor to tune both the photoresponse time and photocurrent based on light modulation, and probes the primary reason for the distinct modulation results between the 5 and 11 nm C 60 devices.
