TL;DR: It is demonstrated that the energy landscape of quantum well and quantum dot infrared photodetectors can be mimicked from a mixture of mercury selenide and mercury telluride nanocrystals, and the concept of wavefunction engineering at the device scale can now be applied for the design of complex colloidal nanocrystal-based devices.
Journal ArticleDOI

Nicolas Goubet,Nicolas Goubet,Amardeep Jagtap,Clément Livache,Clément Livache,Bertille Martinez,Bertille Martinez,Hervé Portalès,Xiang Zhen Xu,Xiang Zhen Xu,Ricardo P. S. M. Lobo,Ricardo P. S. M. Lobo,Benoit Dubertret,Benoit Dubertret,Emmanuel Lhuillier +14 more
TL;DR: A new synthetic procedure for the growth of HgTe, HgSe, and HgS nanocrystals, with strong size tunability from 5 to 200 nm, is developed, which is used to tune the absorption of the nanocry crystals all over the infrared range up to terahertz.
Journal ArticleDOI
Intraband Mid-Infrared Transitions in Ag2Se Nanocrystals: Potential and Limitations for Hg-Free Low-Cost Photodetection
Junling Qu,Nicolas Goubet,Nicolas Goubet,Clément Livache,Clément Livache,Bertille Martinez,Bertille Martinez,Dylan Amelot,Charlie Gréboval,Audrey Chu,Julien Ramade,Hervé Cruguel,Sandrine Ithurria,Mathieu G. Silly,Emmanuel Lhuillier +14 more
TL;DR: In this article, the authors investigated Ag2Se nanoparticles presenting intraband transition between 3 and 15 µm with photoemission and infrared spectroscopy, and proposed an electronic spectrum of the material in the absolute energy scale.
Journal ArticleDOI
Road Map for Nanocrystal based Infrared Photodetectors
TL;DR: The current state of the art relative to nanocrystal based IR sensing is summarized and the main materials, devices and industrial challenges which will have to be addressed over the 5 next years are stressed.
Journal ArticleDOI

Bertille Martinez,Bertille Martinez,Julien Ramade,Clément Livache,Clément Livache,Nicolas Goubet,Nicolas Goubet,Audrey Chu,Charlie Gréboval,Junling Qu,William L. Watkins,Loïc Becerra,Erwan Dandeu,Jean Louis Fave,Christophe Méthivier,Emmanuelle Lacaze,Emmanuel Lhuillier +16 more
TL;DR: In this paper, an extended short-wave IR (2.5 µm cut-off) is focused on to expand the capabilities of InGaAs, while using HgTe nanocrystals as the active material.
