Maximum screening fields of superconducting multilayer structures

open access: yesAIP Advances, 2015
It is shown that a multilayer comprised of alternating thin superconducting and insulating layers on a thick substrate can fully screen the applied magnetic field exceeding the superheating fields Hs of both the superconducting layers and the substrate ...

Plasmon resonance in multilayer graphene nanoribbons [PDF]

open access: yesLaser & Photonics Reviews, 2015
AbstractPlasmon resonances in nanopatterned single‐layer graphene nanoribbons (SL‐GNRs), double‐layer graphene nanoribbons (DL‐GNRs) and triple‐layer graphene nanoribbons (TL‐GNRs) are studied experimentally using ‘realistic’ graphene samples.

Resonance effects in correlated multilayer heterostructures [PDF]

open access: yesPhysical Review B, 2016
We study the occurrence of negative differential conductance induced by resonance effects in a model for a multilayer heterostructure. In particular, we consider a system consisting of several correlated and non-correlated monoatomic layers, sandwiched between two metallic leads.

Single- and two-photon absorption induced all-optical control of gallium selenide integrated silicon nitride photonic devices in the 700–800 nm wavelength range

open access: yesAPL Photonics, 2023
In this work, we report single- and two-photon absorption (TPA) induced transmission and resonance modulation in a multilayer gallium selenide (GaSe) integrated silicon nitride (Si3N4) waveguide and ring resonator operating in the 700–800 nm wavelength ...
