Semi-Transparent Image Sensors for Eye-Tracking Applications
Gabriel Mercier, Emre O. Polat, Shengtai Shi +4
Image sensors hold a pivotal role in society due to their ability to capture vast amounts of information. Traditionally, image sensors are opaque due to light absorption in both th…
Colloidal quantum dot infrared lasers featuring sub-single-exciton threshold and very high gain
Nima Taghipour, Mariona Dalmases, Guy L. Whitworth +3
The use of colloidal quantum dots (CQDs) as a gain medium in infrared laser devices has been underpinned by the need for high pumping intensities, very short gain lifetimes and low…
Low-threshold, highly stable colloidal quantum dot short-wave infrared laser enabled by suppression of trap-assisted Auger recombination
Nima Taghipour, Guy L. Whitworth, Andreas Othonos +5
Pb-chalcogenide colloidal quantum dots (CQDs) are attractive materials to be used as tuneable laser media across the infrared spectrum. However, excessive nonradiative Auger recomb…
Highly Efficient, Bright and Stable Colloidal Quantum Dot Short-Wave Infrared Light Emitting Diodes
Santanu Pradhan, Mariona Dalmases, Ayse-Bilgehan Baspinar +1
Unbalanced charge injection is deleterious for the performance of colloidal quantum dot (CQD) light emitting diodes (LEDs) as it deteriorates the quantum efficiency (QE), brightnes…
Single-Exciton Gain and Stimulated Emission across the Infrared Telecom Band from Robust Heavily-doped PbS Colloidal Quantum Dots
Sotirios Christodoulou, Iñigo Ramiro, Andreas Othonos +6
Materials with optical gain in the infrared are of paramount importance for optical communications, medical diagnostics and silicon photonics. The current technology is based eithe…
