Defect Passivation of CsPbBr3 with AgBr for High‐Performance All‐Inorganic Perovskite Solar Cells

open access: yesAdvanced Energy & Sustainability Research, 2021
CsPbBr3‐based perovskite solar cells possess both high humidity and temperature tolerance, and also have excellent long‐term stability in air, but the defect states in the bulk perovskite are always an obstacle for further improvement of their efficiency.

Quantum transport in a single molecular transistor at finite temperature

open access: yesScientific Reports, 2021
We study quantum transport in a single molecular transistor in which the central region consists of a single-level quantum dot and is connected to two metallic leads that act as a source and a drain respectively. The quantum dot is considered to be under

Quantum-dot devices and Quantum-dot Cellular Automata

open access: yesJournal of the Franklin Institute, 1997
We discuss novel nanoelectronic architecture paradigms based on cells composed of coupled quantum-dots. Boolean logic functions may be implemented in specific arrays of cells representing binary information, the so-called Quantum-Dot Cellular Automata (QCA).

Quantum dot enabled thermal imaging of optofluidic devices [PDF]

open access: yes, 2012
Quantum dot thermal imaging has been used to analyse the chromatic dependence of laser-induced thermal effects inside optofluidic devices with monolithically integrated near-infrared waveguides. We demonstrate how microchannel optical local heating plays
