Multi-Photon Transitions in Coupled Plasmon-Cyclotron Resonance Measured by Millimeter-Wave Reflection
Jie Zhang, Ruiyuan Liu, Rui-Rui Du +2
We construct a low-temperature microwave waveguide interferometer for measuring high-frequency properties of two-dimensional electron gases (2DEGs). Coupled plasmon-cyclotron reson…
A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond
Deji Akinwande, Christopher J. Brennan, J. Scott Bunch +17
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitrid…
Probing the semiconductor to semimetal transition in InAs/GaSb double quantum wells by magneto-infrared spectroscopy
Y. Jiang, S. Thapa, G. D. Sanders +10
We perform a magneto-infrared spectroscopy study of the semiconductor to semimetal transition of InAs/GaSb double quantum wells from the normal to the inverted state. We show that…
Current noise enhancement: channel mixing and possible nonequilibrium phonon backaction in atomic-scale Au junctions
Loah A. Stevens, Pavlo Zolotavin, Ruoyu Chen +1
We report measurements of the bias dependence of the Fano factor in ensembles of atomic-scale Au junctions at 77 K. Previous measurements of shot noise at room temperature and low…
Global Phase Diagram of a Dirty Weyl Liquid and Emergent Superuniversality
Bitan Roy, Robert-Jan Slager, Vladimir Juricic
Pursuing complementary field-theoretic and numerical methods, we here paint the global phase diagram of a three-dimensional dirty Weyl system. The generalized Harris criterion, aug…
The Quantum Pinch Effect in Semiconducting Quantum Wires: A Bird's-Eye View
Manvir S Kushwaha
Those who measure success with culmination do not seem to be aware that life is a journey not a destination. This spirit is best reflected in the unceasing failures in efforts for…
Tuning Edge States in Strained-Layer InAs/GaInSb Quantum Spin Hall Insulators
Lingjie Du, Tingxin Li, Wenkai Lou +8
We report on a class of quantum spin Hall insulators (QSHIs) in strained-layer InAs/GaInSb quantum wells, in which the bulk gaps are enhanced by up to five folds as compared to the…
Interacting line-node semimetal: Proximity effect and spontaneous symmetry breaking
Bitan Roy
Effects of short-range electronic interactions in a three-dimensional line-node semimetal that supports linearly dispersing quasiparticles around an isolated loop in the Brillouin…
A MoS2-based capacitive displacement sensor for DNA sequencing
A. Smolyanitsky, B. I. Yakobson, T. A. Wassenaar +2
We propose an aqueous functionalized molybdenum disulfide nanoribbon suspended over a solid electrode as the first capacitive displacement sensor aimed at determining the DNA seque…
Plasmon-assisted photoresponse in Ge-coated bowtie nanojunctions
Kenneth M. Evans, Pavlo Zolotavin, Douglas Natelson
We demonstrate plasmon-enhanced photoconduction in Au bowtie nanojunctions containing nanogaps overlaid with an amorphous Ge film. The role of plasmons in the production of nanogap…
Interplay of bias-driven charging and the vibrational Stark effect in molecular junctions
Yajing Li, Pavlo Zolotavin, Peter Doak +3
We observe large, reversible, bias driven changes in the vibrational energies of PCBM, based on simultaneous transport and surface-enhanced Raman spectroscopy (SERS) measurements o…
Valley Trion Dynamics in Monolayer MoSe
Feng Gao, Yongji Gong, Michael Titze +3
Charged excitons called trions play an important role in the fundamental valley dynamics in the newly emerging 2D semiconductor materials. We used ultrafast pump- probe spectroscop…

Manvir S. Kushwaha
Here we embark on a thorough investigation of the magneto-optical absorption in semiconducting {\em spherical} quantum dots characterized by a confining harmonic potential and an a…
Global phase diagram of a three dimensional dirty topological superconductor
Bitan Roy, Yahya Alavirad, Jay D. Sau
We investigate the phase diagram of a three-dimensional, time-reversal symmetric topological superconductor in the presence of charge impurities and random -wave pairing. Combin…
Magneto-reflection spectroscopy of monolayer transition-metal dichalcogenide semiconductors in pulsed magnetic fields
Andreas V. Stier, Kathleen M. McCreary, Berend T. Jonker +2
We describe recent experimental efforts to perform polarization-resolved optical spectroscopy of monolayer transition-metal dichalcogenide semiconductors in very large pulsed magne…
Topological Protection from Random Rashba Spin-Orbit Backscattering: Ballistic Transport in a Helical Luttinger Liquid
Hong-Yi Xie, Heqiu Li, Yang-Zhi Chou +1
The combination of Rashba spin-orbit coupling and potential disorder induces a random current operator for the edge states of a 2D topological insulator. We prove that charge trans…
