Optoelectronic Devices Based on Colloidal Semiconductor Nanocrystals (NCs)

About this Research Topic

Colloidal nanocrystals (NCs) or quantum dots (QDs) with large absorption coefficients, wide bandgap tunability, and excellent optical properties, are emerging solution-processed semiconductor materials. The NCs made through inexpensive, wet-chemical synthetic procedures can be deposited on substrates at room temperature, which endows them as promising building blocks for the fabrication of low-cost, large-area, and flexible optoelectronic devices. Up to now, NCs, including classical II-VI, III-V, IV-VI (CdSe, InP, PbS, etc.) semiconductors and recently developed lead halide perovskites (LHPs) (CsPbX3, X=Cl, Br, I), have been widely used in light-emitting diode, solar cell, photodetector, field-effect transistor, and laser etc. The research of the optoelectronic applications of NCs has also led to unprecedented development in the fields of nanomaterial synthesis, surface science, photoexcited carrier dynamics, functional device integration and others.

We welcome investigators to contribute with Original Research Articles as well as Review Articles that will stimulate the continuing efforts to exploit the great potential of NCs based optoelectronic applications and motivate the development of related fields.

Main suggested target topics include (but are not limited to) the following:

- Nanocrystals synthesis
- Surface science of nanocrystals
- Self-assembly of nanocrystals
- Photoexcited carrier dynamics of nanocrystals
- Optoelectronic applications based on nanocrystals


Keywords: nanocrystals, quantum dots, optoelectronic applications, device performance, surface science, photoexcited carrier dynamics


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
