Disorder-broadened topological Hall phase and anomalous Hall scaling in FeGe
Chaman Gupta, Chris Matsumura, Hongbin Yang +9
Magnetic skyrmions are topologically protected spin textures that are promising candidates for low-power spintronic memory and logic devices. Realizing skyrmion-based devices requi…
Observation of room-temperature ferroelectricity in elemental Te nanowires
Jinlei Zhang, Jiayong Zhang, Yaping Qi +10
Ferroelectrics are essential in low-dimensional memory devices for multi-bit storage and high-density integration. A polar structure is a necessary premise for ferroelectricity, ma…
Simultaneous imaging of dopants and free charge carriers by STEM-EELS
Hongbin Yang, Andrea Konečná, Xianghan Xu +4
Doping inhomogeneities in solids are not uncommon, but their microscopic observation and understanding are limited due to the lack of bulk-sensitive experimental techniques with hi…
Humble planar defects in SiGe nanopillars
Hongbin Yang, Shang Ren, Sobhit Singh +5
We report a new \{001\} planar defect found in SiGe nanopillars. The defect structure, determined by atomic resolution electron microscopy, matches the Humble defect model proposed…
Low-loss tunable infrared plasmons in the high-mobility perovskite (Ba,La)SnO
Hongbin Yang, Andrea Konečná, Xianghan Xu +4
BaSnO exhibits the highest carrier mobility among perovskite oxides, making it ideal for oxide electronics. Collective charge carrier oscillations, plasmons, are expected to ar…
Observation of Pines' Demon in SrRuO
A. A. Husain, E. W. Huang, M. Mitrano +11
The characteristic excitation of a metal is its plasmon, which is a quantized collective oscillation of its electron density. In 1956, David Pines predicted that a distinct type of…
