Evidence of Polaron Formation in Halide Perovskites via Carrier Effective Mass Measurements

Di Bao, Qing Hua Chang, Bingbing Chen, Xiaoxuan Chen et autres

A combination of transient spectroscopy techniques provides an estimate of the time-resolved effective carrier mass and carrier-phonon coupling constant in a photovoltaic absorber, here applied to lead-halide perovskites.

Tracking carrier and exciton dynamics in mixed-cation lead mixed-halide perovskite thin films

Qing Hua Chang, Di Bao, Bingbing Chen, Hongwei Hu et autres

Abstract Mixed-cation lead mixed-halide perovskites simultaneously possess structural stability and high power conversion efficiency. A thorough study of both carrier and exciton dynamics is needed to understand the photophysical properties that underpin its superior photovoltaic performance. By utilizing a broadband transient absorption …

Studying spin–charge conversion using terahertz pulses

Liang Cheng, Ziqi Li, Daming Zhao, Elbert E. M. Chia

Spin–charge conversion is a spin–orbit coupling phenomena where electrical currents can generate transverse spin currents and vice versa. It is one of the central topics in spintronics and widely applied to manipulate the spin and charge degrees of freedom in materials. Previous …

Observation of interacting polaronic gas behavior in Ta-doped TiO2 thin films via terahertz time-domain spectroscopy

Liang Cheng, Tarapada Sarkar, James Lourembam, Roxanne Tutchton et autres

Transparent conductive oxides (TCOs)—materials that have the twin desirable features of high optical transmission and electrical conductivity—play an increasingly significant role in the fields of photovoltaics and information technology. As an excellent TCO, Ta-doped anatase TiO2 shows great promise for a wide …

Quenching of the relaxation pathway in the Weyl semimetal TaAs

Jiayun Liu, Liang Cheng, Daming Zhao, Xiaoxuan Chen et autres

Since tantalum arsenide (TaAs) has been experimentally verified as a Weyl semimetal, intensive research has been devoted to study of the unique properties of the material. Despite this, the ultrafast dynamics of TaAs is still not very well understood. In this work, …
