Atomically Thin CrCl3: An in-Plane Layered Antiferromagnetic Insulator
Xinghan Cai, Tiancheng Song, Nathan P. Wilson +10
The recent discovery of magnetism in atomically thin layers of van der Waals (vdW) crystals has created new opportunities for exploring magnetic phenomena in the two-dimensional (2…
Imaging Quantum Spin Hall Edges in Monolayer WTe2
Yanmeng Shi, Joshua Kahn, Ben Niu +9
A two-dimensional (2D) topological insulator (TI) exhibits the quantum spin Hall (QSH) effect, in which topologically protected spin-polarized conducting channels exist at the samp…
Voltage Control of a van der Waals Spin-Filter Magnetic Tunnel Junction
Tiancheng Song, Matisse Wei-Yuan Tu, Caitlin Carnahan +8
Atomically thin chromium triiodide (CrI3) has recently been identified as a layered antiferromagnetic insulator, in which adjacent ferromagnetic monolayers are antiferromagneticall…
Giant Tunneling Magnetoresistance in Spin-Filter van der Waals Heterostructures
Tiancheng Song, Xinghan Cai, Matisse Wei-Yuan Tu +12
Magnetic multilayer devices that exploit magnetoresistance are the backbone of magnetic sensing and data storage technologies. Here we report novel multiple-spin-filter magnetic tu…
Edge conduction in monolayer WTe2
Zaiyao Fei, Tauno Palomaki, Sanfeng Wu +7
A two-dimensional topological insulator (2DTI) is guaranteed to have a helical 1D edge mode in which spin is locked to momentum, producing the quantum spin Hall effect and prohibit…
Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing
M. Mehdi Jadidi, Ryan J. Suess, Cheng Tan +9
Hot electron effects in graphene are significant because of graphene's small electronic heat capacity and weak electron-phonon coupling, yet the dynamics and cooling mechanisms of…
Electronic transport properties of Ir-decorated graphene
Yilin Wang, Shudong Xiao, Xinghan Cai +3
Graphene decorated with 5d transitional metal atoms is predicted to exhibit many intriguing properties; for example iridium adatoms are proposed to induce a substantial topological…
Neutral-current Hall effects in disordered graphene
Yilin Wang, Xinghan Cai, Janice Reutt-Robey +1
A non-local Hall bar geometry is used to detect neutral-current Hall effects in graphene on silicon dioxide. Disorder is tuned by the addition of Au or Ir adatoms in ultra-high vac…
Approaching the Limits of Transparency and Conductivity in Graphitic Materials through Lithium Intercalation
Wenzhong Bao, Jiayu Wan, Xiaogang Han +9
Various bandstructure engineering methods have been studied to improve the performance of graphitic transparent conductors; however none demonstrated an increase of optical transmi…
Sensitive Room-Temperature Terahertz Detection via Photothermoelectric Effect in Graphene
Xinghan Cai, Andrei B. Sushkov, Ryan J. Suess +10
Terahertz (THz) radiation has uses from security to medicine; however, sensitive room-temperature detection of THz is notoriously difficult. The hot-electron photothermoelectric ef…
High Mobility Ambipolar MoS2 Field-Effect Transistors: Substrate and Dielectric Effects
Wenzhong Bao, Xinghan Cai, Dohun Kim +2
We fabricate MoS2 field effect transistors on both SiO2 and polymethyl methacrylate (PMMA) dielectrics and measure charge carrier mobility in a four-probe configuration. For multil…
