Unconventional cross-step growth of monolayer MoS 2 on sapphire

Y. Q. Zhang, Xudan Zhang, Xuhui Wang, Xiuzhen Li et autres

Regarding thin film growth, it has been widely recognized that the film typically follows the surface texture and high sharp steps potentially lead to growth termination and film discontinuity. Here, we demonstrate an abnormality that monolayer MoS 2 grown on C -plane …

Integrated Spatiotemporal Multiscale- Multiphysics-Uncertainty Simulation for Controlling Variability in RRAM Devices

Ziyan Liao, Zhiheng Huang, Min Xiao, Yuezhong Meng et autres

Resistive random access memory (RRAM) is a leading candidate for next-generation nonvolatile memory and neuromorphic computing. However, its performance is limited by inherent switching variability and uncertainties in spatiotemporal multiscale materials and processes. This study integrates multiphysics and multiscale modeling with uncertainty …

Origin of Nonlinear Circular Photocurrent in 2D Semiconductor MoS 2

Yanchong Zhao, Fengyu Chen, Jing Liang, M. S. Bahramy et autres

Nonlinear photogalvanic effects in two-dimensional materials, particularly the nonlinear circular photocurrents (NCPs) that belong to the helicity-dependent spin photocurrents, have sparked enormous research interest. Although notable progress has been witnessed, the underling origin of NCPs remains elusive. Here, we present systematic photocurrent …
