Real Space Visualization of Order-Disorder Transition in BaTiO3
Yang Zhang, Xiaoming Shi, Suk Hyun Sung +4
Ferroelectricity in BaTiO3 was observed nearly eighty years ago, but the mechanism underlying its ferroelectric-paraelectric phase transition remains elusive. The order-disorder tr…
Giant Rashba splitting in PtTe/PtTe heterostructure
Runfa Feng, Yang Zhang, Jiaheng Li +11
Achieving a large spin splitting is highly desirable for spintronic devices, which often requires breaking of the inversion symmetry. However, many atomically thin films are centro…
Unveiling an in-plane Hall effect in rutile RuO films
Meng Wang, Jianbing Zhang, Di Tian +2
The in-plane-magnetic-field-induced Hall effect (IPHE) observed in Weyl semimetals and PT-symmetric antiferromagnets has attracted increasing attention, as it breaks the stereotype…
Sub-nanometer depth resolution and single dopant visualization achieved by tilt-coupled multislice electron ptychography
Zehao Dong, Yang Zhang, Chun-Chien Chiu +8
Real-space imaging of three-dimensional atomic structures is a critical yet challenging task in materials science. Although scanning transmission electron microscopy has achieved s…
