TL;DR: In this article, the optical properties of different InP nanowire (NW) array solar cells with different axial p−i−n junction designs were investigated, and a glancing angle sputtering deposition technique was developed to enable a direct visualization of the p−n junctions in the vertical array of InP NW solar cells using electron beam-induced current (EBIC) technique.

TL;DR: Doping and nanowire length are identified as key controllable parameters determining lasing behavior, with reliable room-temperature lasing occurring for p ≳ 3 × 1018 cm-3 and lengths of ≳4 μm, and a best-in-class core-only near-infrared nanowires lasing threshold of ∼10 μJ cm-2 is reported.

TL;DR: In this paper, the effect of the size distribution of nanoparticles on the performance of plasmonic polycrystalline Si thin-film solar cells was studied. And the performance was attributed to a broader scattering cross section of the array owing to a broad particle size distribution and a higher nanoparticle coverage.

TL;DR: In this paper, a photodetector based on exfoliated Ta2NiSe5 nanoflake was demonstrated, which exhibits a broadband photo-response from 405-nm to 4300-nm.

TL;DR: In this paper, experimental results on spontaneous emission rates from InGaAs quantum dot lasers that can be explained theoretically by considering the influence of nonradiative mixed state recombinations in the quantum dot-wetting layer system are presented.
