Abstract As they have gained maturity, colloidal nanocrystals (NCs) also expand the spectral range over of which could be used for photonic and optoelectronic applications. In particular, infrared use NCs has become utmost interest to develop cost‐effective alternatives current technologies. It is then critical not let material dictate light–matter interaction, why coupling cavities been proposed. For NCs, this approach first devoted control absorption with in mind increase signal magnitude...
Abstract The development of optoelectronic devices based on III–V semiconductor colloidal quantum dots (CQDs) is highly sought after due to their reduced toxicity. While conventional CQDs (II–VI semiconductors, halide perovskites) have achieved impressive technological leaps since discovery, the most mature these compounds contain toxic heavy metal elements (Cd, Hg, or Pb), which are undesirable for safe industrial scale applications. strong covalent bonds like InP, InAs, InSb prevent...
The use of nanocrystals in optoelectronics strongly relies on the ability to design photodiodes, which requires advanced knowledge their electronic structure and offers even greater potential when that can be finely tuned. For traditional semiconductors, this degree freedom is achieved through doping, obtained mostly via introduction extrinsic impurities. When it comes colloidal quantum dots, capacity lost carrier density control best thanks surface ligand exchanges. Tuning capping molecule...
