Current-enhanced broadband THz emission from spintronic devices
Mengji Chen, Yang Wu, Yang Liu +5
An ultra-broadband THz emitter covering a wide range of frequencies from 0.1 to 10 THz is highly desired for spectroscopy applications. So far, spintronic THz emitters have been pr…
Ultrafast Spin-To-Charge Conversion at the Surface of Topological Insulator Thin Films
Xinbo Wang, Liang Cheng, Dapeng Zhu +11
Strong spin-orbit coupling, resulting in the formation of spin-momentum-locked surface states, endows topological insulators with superior spin-to-charge conversion characteristics…
Terahertz Emission from Compensated Magnetic Heterostructures
Mengji Chen, Rahul Mishra, Yang Wu +2
Terahertz emission spectroscopy (TES) has recently played an important role in unveiling the spin dynamics at a terahertz (THz) frequency range. So far, ferromagnetic (FM)/nonmagne…
Direct visualization of current induced spin accumulation in topological insulators
Yang Liu, Jean Besbas, Yi Wang +10
Charge-to-spin conversion in various material systems is the key for the fundamental understanding of spin-orbitronis as well as the development of efficient means to manipulate th…
