Spin Coherence and Spin Relaxation in Hybrid Organic-Inorganic Lead and Mixed Lead-Tin Perovskites
Haochen Zhang, Zehua Zhai, Zhixuan Bi +5
Metal halide perovskites make up a promising class of materials for semiconductor spintronics. Here we report a systematic investigation of coherent spin precession, spin dephasing…
Revealing unusual bandgap shifts with temperature and bandgap renormalization effect in phase-stabilized metal halide perovskite thin films
Haochen Zhang, Zhixuan Bi, Zehua Zhai +11
Hybrid organic-inorganic metal halide perovskites are emerging materials in photovoltaics, whose bandgap is one of the most crucial parameters governing their light harvesting perf…
Real-time observation of magnetization and magnon dynamics in a two-dimensional topological antiferromagnet MnBi2Te4
F. Michael Bartram, Meng Li, Liangyang Liu +9
Atomically thin van der Waals magnetic materials have not only provided a fertile playground to explore basic physics in the two-dimensional (2D) limit but also created vast opport…
Security evaluation of cyber networks under advanced persistent threats
Lu-Xing Yang, Pengdeng Li, Xiaofan Yang +3
This paper is devoted to measuring the security of cyber networks under advanced persistent threats (APTs). First, an APT-based cyber attack-defense process is modeled as an indivi…
Assessing the risk of advanced persistent threats
Xiaofan Yang, Tianrui Zhang, Lu-Xing Yang +2
As a new type of cyber attacks, advanced persistent threats (APTs) pose a severe threat to modern society. This paper focuses on the assessment of the risk of APTs. Based on a dyna…
Doppler velocimetry of spin propagation in a two-dimensional electron gas
Luyi Yang, J. D. Koralek, J. Orenstein +3
Controlling the flow of electrons by manipulation of their spin is a key to the development of spin-based electronics. While recent demonstrations of electrical-gate control in spi…
