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: In this paper, Fe/Mg co-doping is proposed for the first time to improve the thermochromic performance of vanadium dioxide (VO2) films.

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: In this paper, the authors investigated Al-doped VO 2 films as thermochromic coatings on glass substrates by DC magnetron sputtering and found that adding Al 3+ ions into VO 2 can generate groups of polygonal grains and nanowire clusters, apart from routinely reducing the valence and decreasing the grain size.

TL;DR: Al-doped VO2 films were prepared on (111) directional silicon substrate, which rapidly counteracted the absorption peak and exhibited widely modulating properties and a valence reduction of the vanadium element, which was caused by the valence difference between V and Al atoms.
