Robust negative longitudinal magnetoresistance and spin-orbit torque in sputtered Pt3Sn topological semimetal
Delin Zhang, Wei Jiang, Hwanhui Yun +11
Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states…
Charge-to-spin conversion in twisted graphene/WSe heterostructures
Seungjun Lee, D. J. P. de Sousa, Young-Kyun Kwon +4
We investigate the twist angle dependence of spin-orbit coupling (SOC) proximity effects and charge-to-spin conversion (CSC) in graphene/WSe heterostructures from first princip…
Convert widespread paraelectric perovskite to ferroelectrics
Hongwei Wang, Fujie Tang, Massimiliano Stengel +4
While nature provides a plethora of perovskite materials, only a few exhibits large ferroelectricity and possibly multiferroicity. The majority of perovskite materials have the non…
Near-field probing of image phonon-polaritons in hexagonal boron nitride on gold crystals
Sergey G. Menabde, Sergejs Boroviks, Jongtae Ahn +7
Near-field mapping has been widely used to study hyperbolic phonon-polaritons in van der Waals crystals. However, an accurate measurement of the polaritonic loss remains challengin…
ZrTe2/CrTe2: an epitaxial van der Waals platform for spintronics
Yongxi Ou, Wilson Yanez, Run Xiao +12
The rapid discovery of two-dimensional (2D) van der Waals (vdW) quantum materials has led to heterostructures that integrate diverse quantum functionalities such as topological pha…
Simple linear response model for predicting energy band alignment of two-dimensional vertical heterostructure
Javad G. Azadani, Seungjun Lee, Hyeong-Ryul Kim +4
The Anderson and midgap models are often used in the study of semiconductor heterojunctions, but for van der Waals (vdW) vertical heterostructures they have shown only very limited…
