Special Issue "PbS Colloidal Quantum Dots and Their Applications"
Deadline for manuscript submissions: closed (15 February 2020).
Interests: Design, fabrication and characterization of electronic and optoelectronic devices, compatible with silicon technology and relevant to sensing, optical communications and imaging. It includes the synthesis, modeling and characterization of novel materials and nanomaterials for device applications (SiGe alloys and superlattices, group IV and III-V semiconductors, colloidal quantum dots). Other research fields are gas sensors, photovoltaics and optical countermeasures in the mid-infrared
Colloidal quantum dots (CQD) are semiconductor nanocrystals that are synthesized and suspended in solution. Their typical small size produces three-dimensional quantum confinement, enabling band-gap engineering and dramatically enhancing optical emission and absorption with tunable properties by the quantum size effect. In addition, due to their solution processability, CQDs allow simple, low temperature fabrication and are compatible with a wide variety of substrates, including polymers, glass and silicon.
Thanks to their unique electronic and optical properties and their simple fabrication process, CQDs have attracted lot of interest for a wide variety of devices, including light emitting diodes, photodetectors, solar cells and transistors.
In this framework, lead sulphide (PbS) CQDs, spanning the visible and the near infrared, are the among the most advanced colloidal materials in terms of both monodispersion and reproducibility. Over the past 20 years, CQD technology has dramatically advanced from the pioneering research and significant progress has been made in terms of both theory and experiments, with several devices demonstrating performance comparable with their bulk semiconductor counterparts. However, challenges remain to achieve full control of carrier type and concentration, mobility and defect states, as well as to improve stability under operation.
The goal of this Special Issue is to attract world-leading researchers in the area of PbS colloidal quantum dots focusing on the latest advances in both material synthesis and device fabrication and applications.
Review papers, original contributions focused on material issues, new device architectures, proof-of-concept, integration and, especially, suitable and potential applications of PbS CQD-based devices are welcome.
