Topological-insulator-based terahertz modulator
Xinbo Wang,Liang Cheng,Yang Wu,Dapeng Zhu,Lan Wang,Jian-Xin Zhu,Hyunsoo Yang,Elbert E. M. Chia +7 more
TL;DR: This work experimentally demonstrates an electronically-tunable terahertz intensity modulator based on Bi1:5Sb0:5Te1:8Se1:2 single crystal, one of the most insulating topological insulators, and proposes that the extraordinarily large modulation is a consequence of thermally-activated carrier absorption in the semiconducting bulk states.
Journal ArticleDOI

TL;DR: Results from an analysis of all data taken by the bicep2/Keck CMB polarization experiments up to and including the 2015 observing season are presented, showing the strongest constraints to date on primordial gravitational waves.
Journal ArticleDOI
Direct visualization of current-induced spin accumulation in topological insulators.
Yang Liu,Jean Besbas,Yi Wang,Pan He,Mengji Chen,Dapeng Zhu,Yang Wu,Jong Min Lee,Lan Wang,Jisoo Moon,Nikesh Koirala,Seongshik Oh,Hyunsoo Yang +12 more
TL;DR: Spatial imaging of current-induced spin accumulation at the edges of Bi2Se3 and BiSbTeSe2 topological insulators as well as Pt by a scanning photovoltage microscope at room temperature points towards a better understanding of the interaction between spins and circularly polarized light.
Journal ArticleDOI
Surface-Energy Engineering of Graphene
Young Jun Shin,Yingying Wang,Han Huang,Gopinadhan Kalon,Andrew T. S. Wee,Zexiang Shen,Charanjit S. Bhatia,Hyunsoo Yang +7 more
TL;DR: By using a low-power oxygen plasma treatment, the wettability of graphene is improved without additional damage, which can solve the adhesion issues involved in the fabrication of graphene devices.
Journal ArticleDOI
Direct observation of the Dzyaloshinskii-Moriya interaction in a Pt/Co/Ni film.
Kai Di,V. L. Zhang,Hock Siah Lim,Ser Choon Ng,Meng Hau Kuok,Jiawei Yu,Jungbum Yoon,Xuepeng Qiu,Hyunsoo Yang +8 more
TL;DR: Linewidth measurements reveal that the lifetime of the magnons is asymmetric with respect to their counter-propagating directions, and the lifetime asymmetry is dependent on the magnon frequency, being more pronounced, the higher the frequency.
