The origin of uniaxial negative thermal expansion in layered perovskites [PDF]

, 2017
Why is it that ABO3 perovskites generally do not exhibit negative thermal expansion (NTE) over a wide temperature range, whereas layered perovskites of the same chemical family often do?

Rewritable High-Mobility Electrons in Oxide Heterostructure of Layered Perovskite/Perovskite

ACS Applied Materials & Interfaces, 2021
Perovskite oxide SrTiO3 can be electron-doped and exhibits high mobility by introducing oxygen vacancies or dopants such as Nb or La. A reversible after-growth tuning of high mobility carriers in SrTiO3 is highly desired for the applications in high-speed electronic devices.
