Central role of domain wall depinning for perpendicular magnetization switching driven by spin torque from the spin Hall effect
O. J. Lee, L. Q. Liu, C. F. Pai +4
We study deterministic magnetic reversal of a perpendicularly magnetized Co layer in a Co/MgO/Ta nano-square driven by spin Hall torque from an in-plane current flowing in an under…
Dissipation in ultrahigh quality factor SiN membrane resonators
S. Chakram, Y. S. Patil, L. Chang +1
We study the optomechanical properties of stoichiometric SiN resonators through a combination of spectroscopic and interferometric imaging techniques. At room temperature, we demon…
Van Hove Singularities and Excitonic Effects in the Optical Conductivity of Twisted Bilayer Graphene
Robin W. Havener, Yufeng Liang, Lola Brown +2
We report a systematic study of the optical conductivity of twisted bilayer graphene (tBLG) across a large energy range (1.2 eV to 5.6 eV) for various twist angles, combined with f…
Simultaneous Electrical and Optical Readout of Graphene-Coated High Q Silicon Nitride Resonators
V. P. Adiga, R. De Alba, I. R. Storch +8
We have fabricated and tested mechanical resonators consisting of a single-atomic-layer of graphene deposited on suspended silicon nitride membranes. With the addition of the graph…
Experimental demonstration of continuous electronic structure tuning via strain in atomically thin MoS2
Keliang He, Charles Poole, Kin Fai Mak +1
We demonstrate the continuous tuning of the electronic structure of atomically thin MoS2 on flexible substrates by applying a uniaxial tensile strain. A redshift at a rate of ~70 m…
A quasi-linear spin-torque nano-oscillator via enhanced negative feedback of power fluctuations
O. J. Lee, P. M. Braganca, V. S. Pribiag +2
We report an approach to improving the performance of spin torque nano-oscillators (STNOs) that utilizes power-dependent negative feedback to achieve a significantly enhanced dynam…
Spin-Torque Generation in Topological-Insulator-Based Heterostructures
Mark H Fischer, Abolhassan Vaezi, Aurelien Manchon +1
Heterostructures utilizing topological insulators exhibit a remarkable spin-torque efficiency. However, the exact origin of the strong torque, in particular whether it stems from t…
Strain Solitons and Topological Defects in Bilayer Graphene
Jonathan S. Alden, Adam W. Tsen, Pinshane Y. Huang +5
Spontaneous symmetry-breaking, where the ground state of a system has lower symmetry than the underlying Hamiltonian, is ubiquitous in physics. It leads to multiply-degenerate grou…
Design and operation of a microfabricated phonon spectrometer utilizing superconducting tunnel junctions as phonon transducers
Obafemi O. Otelaja, Jared B. Hertzberg, Mahmut Aksit +1
In order to fully understand nanoscale heat transport it is necessary to spectrally characterize phonon transmission in nanostructures. Towards this goal we have developed a microf…
Confined Plasmons in Graphene Microstructures: Experiments and Theory
Jared H. Strait, Parinita S. Nene, Wei-Min Chan +5
Graphene, a two-dimensional material with a high mobility and a tunable conductivity, is uniquely suited for plasmonics. The frequency dispersion of plasmons in bulk graphene has b…
Observation and Spectroscopy of a Two-Electron Wigner Molecule in an Ultra-Clean Carbon Nanotube
S. Pecker, F. Kuemmeth, A. Secchi +4
Coulomb interactions can have a decisive effect on the ground state of electronic systems. The simplest system in which interactions can play an interesting role is that of two ele…
