Multiplexed digital holography for fluid surface profilometry
August Geelmuyden, Vitor S. Barroso, Sreelekshmi C. Ajithkumar +2
Digital holography (DH) has been widely used for imaging and characterization of micro and nanostructures in materials science and biology and has the potential to provide high-res…
Low-Energy Switching of Antiferromagnetic CuMnAs/ GaP Using sub-10 Nanosecond Current Pulses
K. A. Omari, L. X. Barton, O. Amin +4
The recently discovered electrical-induced switching of antiferromagnetic (AF) materials that have spatial inversion asymmetry has enriched the field of spintronics immensely and o…
Ultrafast strain-induced charge transport in semiconductor superlattices
F. Wang, C. L. Poyser, M. T. Greenaway +5
We investigate the effect of hypersonic (> 1 GHz) acoustic phonon wavepackets on electron transport in a semiconductor superlattice. Our quantum mechanical simulations demonstrate…
Ultrafast insulator-to-metal transition in VO nanostructures assisted by picosecond strain pulses
Ia. A. Mogunov, F. Fernández, S. Lysenko +4
Strain engineering is a powerful technology which exploits stationary external or internal stress of specific spatial distribution for controlling the fundamental properties of con…
Hypersonic properties of monodisperse spherical mesoporous silica particles
D. A. Eurov, D. A. Kurdyukov, E. Yu. Stovpiaga +8
We use the picosecond acoustic pump-probe technique to study the elastic properties of monodispersemesoporous silica spheres filled with nickel and deposited in the form of opal-li…
Modulation of a surface plasmon-polariton resonance by sub-terahertz diffracted coherent phonons
Christian Brüggemann, Andrey V. Akimov, Boris A. Glavin +9
Coherent sub-THz phonons incident on a gold grating that is deposited on a dielectric substrate undergo diffraction and thereby induce an alteration of the surface plasmon-polarito…
Using acoustic waves to induce high-frequency current oscillations in superlattices
M. T. Greenaway, A. G. Balanov, D. Fowler +2
We show that GHz acoustic waves in semiconductor superlattices can induce THz electron dynamics that depend critically on the wave amplitude. Below a threshold amplitude, the acous…
Phonon Absorption at the Magneto-Roton Minimum in the Fractional Quantum Hall Effect
CJ Mellor, RH Eyles, JE Digby +6
We have made the first phonon absorption measurements in the fractional quantum Hall régime. Experiments have been conducted on two samples which have similar electron densities bu…
