Atomistic mechanism of carbon nanotube cutting catalyzed by nickel under the electron beam
Irina V. Lebedeva, Thomas W. Chamberlain, Andrey M. Popov +5
The cutting of single-walled carbon nanotubes by an 80 keV electron beam catalyzed by nickel clusters is imaged in situ using aberration-corrected high-resolution transmission elec…
Twist-controlled resonant tunnelling in graphene-boron nitride-graphene heterostructures
A. Mishchenko, J. S. Tu, Y. Cao +19
Recent developments in the technology of van der Waals heterostructures made from two-dimensional atomic crystals have already led to the observation of new physical phenomena, suc…
Optical spin transfer torque driven domain wall motion in ferromagnetic semiconductor
A. J. Ramsay, P. E. Roy, J. A. Haigh +6
We demonstrate optical manipulation of the position of a domain wall in a dilute magnetic semiconductor, GaMnAsP. Two main contributions are identified. Firstly, photocarrier spin…
Microwave Experiments Simulating Quantum Search and Directed Transport in Artificial Graphene
Julian Böhm, Matthieu Bellec, Fabrice Mortessagne +7
A series of quantum search algorithms have been proposed recently providing an algebraic speedup compared to classical search algorithms from to , where is the nu…
Pauli's Principle in Probe Microscopy
Samuel Jarvis, Adam Sweetman, Lev Kantorovich +2
Exceptionally clear images of intramolecular structure can be attained in dynamic force microscopy through the combination of a passivated tip apex and operation in what has become…
Modification of perpendicular magnetic anisotropy and domain wall velocity in Pt/Co/Pt by voltage-induced strain
P. M. Shepley, A. W. Rushforth, M. Wang +2
The perpendicular magnetic anisotropy K, magnetization reversal, and field-driven domain wall velocity in the creep regime are modified in Pt/Co(0.85-1.0 nm)/Pt thin fi…
