Elastic Modulus of Polycrystalline Halide Perovskite Thin Films on Substrates

Autor: Layek, Madhuja, Yang, In Seok, Dai, Zhenghong, Ranka, Anush, Cai, Truong, Sheldon, Brian W., Chason, Eric, Padture, Nitin P.

Using an innovative combination of multi-beam-optical stress-sensor (MOSS) curvature and X-ray diffraction (XRD) techniques, the Young's modulus (E) of polycrystalline MAPbI3 metal-halide perovskite (MHP) thin films attached to Si substrates is estim

Autor: Li, Shunran, Dai, Zhenghong, Li, Linda, Padture, Nitin P., Guo, Peijun

Publikováno v: Rev. Sci. Instrum. 93, 053003 (2022)

Understanding thermal transport at the micro- to nanoscale is crucially important for a wide range of technologies ranging from device thermal management and protection systems to thermal-energy regulation and harvesting. In the past decades, non-con

Photothermally induced, reversible phase transition in methylammonium lead triiodide

Autor: Li, Shunran, Dai, Zhenghong, Kocoj, Conrad A., Altman, Eric I., Padture, Nitin P., Guo, Peijun

Metal halide perovskites (MHPs) are known to undergo several structural phase transitions, from lower to higher symmetry, upon heating. While structural phase transitions have been investigated by a wide range of optical, thermal and electrical metho
