Machine learning-enabled tomographic imaging of chemical short-range atomic ordering

Yue Li, Timoteo Colnaghi, Yilun Gong +13

In solids, chemical short-range order (CSRO) refers to the self-organisation of atoms of certain species occupying specific crystal sites. CSRO is increasingly being envisaged as a…

A Universal Strategy of Perovskite Ink-Substrate Interaction to Overcome the Poor Wettability of a Self-Assembled Monolayer for Reproducible Perovskite Solar Cells

Ashish Kulkarni, Ranjini Sarkar, Samah Akel +6

Perovskite solar cells employing self assembled monolayers such as Me-4PACz as hole transport layer has been reported to demonstrate high device efficiency. However, the poor perov…

Dynamic doping and Cottrell atmosphere optimize the thermoelectric performance of n-type PbTe

Yuan Yu, Chongjian Zhou, Xiangzhao Zhang +9

High thermoelectric energy conversion efficiency requires a large figure-of-merit, zT, over a broad temperature range. To achieve this, we optimize the carrier concentrations of n-…
