Threshold conduction in amorphous phase change materials: effects of temperature
J C Martinez, Ronald A Coutu, Turja Nandy +1
We emphasize the role of temperature in explaining the IV ovonic threshold switching curve of amorphous phase change materials. The Poole-Frankel conduction model is supplemented b…
Nondegenerate and almost hexagonal skyrmion lattices
J. C. Martinez, M. B. A. Jalil
We obtain the lowest energy solutions for the skymion field equations and their corresponding vortex structures. Two nondegenerate solutions emerge with their vortex swirls in oppo…
Topological dynamics and current-induced motion in a skyrmion lattice
J. C. Martinez, M. B. A. Jalil
We study the Thiele equation for current-induced motion in a skyrmion lattice through two soluble models of the pinning potential. Comprised by a Magnus term, a dissipative term an…
Charge fractionalization in biased bilayer graphene
J. C. Martinez, M. B. A. Jalil, S. G. Tan
We study charge fractionalization in bilayer graphene which is intimately related to its zero modes. In the unbiased case, the valley zero modes occur in pairs rendering it unsuita…
Topological charge localization in bilayer graphene induced by an antisymmetric electric potential step
J. C. Martinez, M. B. A. Jalil, S. G. Tan
A charged particle whose energy is less than the electric potential step it is incident upon, is expected to undergo partial reflection and transmission. In bilayer graphene, howev…
Particle-hole Hall effect in graphenelike structures
J. C. Martinez, M. B. A. Jalil, S. G. Tan
We show that a moderately strong constant electric field in the plane of a monolayer graphene sheet can create particle-hole pairs at an observable rate. The pairs undergo zitterbe…
