Investigation of the Self‐Doping Process in HgSe Nanocrystals Open
Colloidal nanocrystals are an interesting platform for the design of low cost infrared optoelectronic materials. In addition to the conventionally observed interband features, doped nanocrystals present intraband transitions, which expand …

Intraband transition in self-doped narrow band gap colloidal quantum dots Open
In this article we discuss the infrared properties of self-doped nanocrystals and in particular the case of HgSe. HgSe colloidal quantum dots have recently been reported for their tunable optical features all over the mid infrared from 3 t…

Surface Control of Doping in Self-Doped Nanocrystals Open
Self-doped nanocrystals raise great interest for infrared (IR) optoelectronics because their optical properties span from near to far IR. However, their integration for photodetection requires a fine understanding of the origin of their do…

Strongly Confined HgTe 2D Nanoplatelets as Narrow Near-Infrared Emitters Open
Two-dimensional colloidal nanoplatelets (NPLs), owing to the atomic-level control of their confined direction (i.e., no inhomogeneous broadening), have demonstrated improved photoluminescence (PL) line widths for cadmium chalcogenide-based…

Nanoplatelets Bridging a Nanotrench: A New Architecture for Photodetectors with Increased Sensitivity Open
Interparticle charge hopping severely limits the integration of colloidal nanocrystals films for optoelectronic device applications. We propose here to overcome this problem by using high aspect ratio interconnects made of wide electrodes …
