Terahertz HgTe Nanocrystals: Beyond Confinement
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
Design of a Unipolar Barrier for a Nanocrystal-Based Short-Wave Infrared Photodiode
Amardeep Jagtap,Bertille Martinez,Bertille Martinez,Nicolas Goubet,Nicolas Goubet,Audrey Chu,Clément Livache,Clément Livache,Charlie Gréboval,Julien Ramade,Julien Ramade,Dylan Amelot,Paul Trousset,Amaury Triboulin,Sandrine Ithurria,Mathieu G. Silly,Benoit Dubertret,Emmanuel Lhuillier +17 more
TL;DR: In this paper, a unipolar barrier was designed from another layer of colloidal quantum dots (CQDs) with a wider band gap to reduce the dark current injection and enhance the signal-to-noise ratio.
Journal ArticleDOI
Short Wave Infrared Devices Based on HgTe Nanocrystals with Air Stable Performances
Amardeep Jagtap,Nicolas Goubet,Nicolas Goubet,Clément Livache,Clément Livache,Audrey Chu,Bertille Martinez,Bertille Martinez,Charlie Gréboval,Junling Qu,Erwan Dandeu,Loïc Becerra,Nadine Witkowski,Sandrine Ithurria,Fabrice Mathevet,Mathieu G. Silly,Benoit Dubertret,Emmanuel Lhuillier +17 more
TL;DR: In this article, an efficient encapsulation method based on a combination of O2 and H2O repellant layers leading to stability over >100 days is presented. But the method is not suitable for low-cost IR detectors.
Journal ArticleDOI
Probing Charge Carrier Dynamics to Unveil the Role of Surface Ligands in HgTe Narrow Band Gap Nanocrystals
Bertille Martinez,Clément Livache,Nicolas Goubet,Amardeep Jagtap,Hervé Cruguel,Abdelkarim Ouerghi,Emmanuelle Lacaze,Mathieu G. Silly,Emmanuel Lhuillier +8 more
TL;DR: In this paper, the influence of a series of ligands, Cl−, SCN−, 1,2-ethanedithiol, 1 4-benzenedithiol and 1-octanethiol, on the photoconductive properties of HgTe nanocrystal thin films is investigated.
Journal ArticleDOI
Emergence of intraband transitions in colloidal nanocrystals [Invited]
Amardeep Jagtap,Clément Livache,Bertille Martinez,Junling Qu,Audrey Chu,Charlie Gréboval,Nicolas Goubet,Emmanuel Lhuillier +7 more
TL;DR: In this paper, the authors discuss the origin of the doping and its tunability as well as how the doping impacts the optical, transport, and photodetection properties of nanocrystals.
