Creation of Localized Skyrmion Bubbles in Co/Pt Bilayers using a Spin Valve Nanopillar
Jennifer L. Grab, Alison E. Rugar, Daniel C. Ralph
We fabricate devices in which a magnetic nanopillar spin valve makes contact to a Co/Pt bilayer thin film with perpendicular magnetic anisotropy, in order to achieve local control…
Active Valley-topological Plasmonic Crystal in Metagate-tuned Graphene
Minwoo Jung, Zhiyuan Fan, Gennady Shvets
A valley plasmonic crystal for graphene surface plasmons (GSPs) is proposed. We demonstrate that a designer metagate, placed within a few nanometers from graphene, can be used to i…
Quantum Critical Transition and Kondo Screening of Magnetic Moments in Graphene
Jinhai Mao, Yuhang Jiang, Po-Wei Lo +7
In normal metals, the magnetic moment of impurity spins disappears below a characteristic Kondo temperature, TK, where coupling with the conduction-band electrons produces an entan…
Vector Electric Field Measurement via Position-Modulated Kelvin Probe Force Microscopy
Ryan P. Dwyer, Louisa M. Smieska, Ali Moeed Tirmzi +1
High-quality spatially-resolved measurements of electric fields are critical to understanding charge injection, charge transport, and charge trapping in semiconducting materials. H…
Ultrafast Graphene Light Emitter
Young Duck Kim, Yuanda Gao, Ren-Jye Shiue +17
Ultrafast electrically driven nanoscale light sources are critical components in nanophotonics. Compound semiconductor-based light sources for the nanophotonic platforms have been…
Fast, low-current spin-orbit torque switching of magnetic tunnel junctions through atomic modifications of the free layer interfaces
Shengjie Shi, Yongxi Ou, S. V. Aradhya +2
Future applications of spin-orbit torque will require new mechanisms to improve the efficiency for switching nanoscale magnetic tunnel junctions (MTJs), while also controlling the…
Tunable multi-electron Pancharatnam phase in intensity interferometry
Disha Wadhawan, Krishanu Roychowdhury, Poonam Mehta +1
Pancharatnam phase was discovered in the context of polarization optics in nineteen fifties. However, its full realization in quantum many-body systems still eludes us. This is pri…
Terahertz spectroscopy of an electron-hole bilayer system in AlN/GaN/AlN quantum wells
H. Condori Quispe, S. M. Islam, S. Bader +7
We describe studies on the nanoscale transport dynamics of carriers in strained AlN/GaN/AlN quantum wells: an electron-hole bilayer charge system with large difference in transport…
Magneto Acoustic Spin Hall Oscillators
Mustafa Mert Torunbalci, Tanay A. Gosavi, Kerem Y. Camsari +1
This paper introduces a novel oscillator that combines the tunability of spin Hall-driven nano oscillators with the high quality factor (Q) of high overtone bulk acoustic wave reso…
Thickness dependence of spin-orbit torques generated by WTe2
David MacNeill, Gregory M. Stiehl, Marcos H. D. Guimaraes +3
We study current-induced torques in WTe2/permalloy bilayers as a function of WTe2 thickness. We measure the torques using both second-harmonic Hall and spin-torque ferromagnetic re…
Hybridization-induced interface states in a topological insulator-magnetic metal heterostructure
Yi-Ting Hsu, Kyungwha Park, Eun-Ah Kim
Recent experiments demonstrating large spin-transfer torques in topological insulator (TI)-ferromagnetic metal (FM) bilayers have generated a great deal of excitement due to their…
Strongly interaction-enhanced valley magnetic response in monolayer WSe2
Zefang Wang, Kin Fai Mak, Jie Shan
Coulomb interaction between electrons lies at the heart of magnetism in solids. In contrast to conventional two-dimensional (2D) systems, electrons in monolayer transition metal di…
High efficiency deep-UV emission at 219 nm from ultrathin MBE GaN/AlN quantum heterostructures
SM Islam, Vladimir Protasenko, Kevin Lee +5
Deep ultraviolet (UV) optical emission below 250 nm (~5 eV) in semiconductors is traditionally obtained from high aluminum containing AlGaN alloy quantum wells. It is shown here th…
Mesoscopic quantum effects in a bad metal, hydrogen-doped vanadium dioxide
Will J. Hardy, Heng Ji, Hanjong Paik +2
The standard treatment of quantum corrections to semiclassical electronic conduction assumes that charge carriers propagate many wavelengths between scattering events, and succeeds…
