Laser induced spin injection to [GeTe/Sb2Te3] superlattice through a TbFeCo film
AIP Advances, 2022 A [GeTe/Sb2Te3] superlattice is known as a topological insulator and it shows magnetic responses such as magneto-optical effect although it does not contain any magnetic element.

Tunable Band Gap in Graphene with a Non-Centrosymmetric Superlattice Potential [PDF]
, 2009 We show that, if graphene is subjected to the potential from an external superlattice, a band gap develops at the Dirac point provided the superlattice potential has broken inversion symmetry.

, 2006 Heat conduction of single-walled carbon nanotubes (SWNTs) isotope-superlattice is investigated by means of classical molecular dynamics simulations. Superlattice structures were formed by alternately connecting SWNTs with different masses. On varying the

Quantum Wire-on-Well (WoW) Cell With Long Carrier Lifetime for Efficient Carrier Transport [PDF]
, 2015 A quantum wire-on-well (WoW) structure, taking advantage of the layer undulation of an In- GaAs/GaAs/GaAsP superlattice grown on a vicinal substrate, was demonstrated to enhance the carrier collection from the confinement levels and extend the carrier ...

Phonon-Induced Polariton Superlattices [PDF]
Physical Review Letters, 2006 We show that the coherent interaction between microcavity polaritons and externally stimulated acoustic phonons forms a tunable polariton superlattice with a folded energy dispersion determined by the phonon population and wavelength. Under high phonon concentration, the strong confinement of the optical and excitonic polariton components in the phonon

Hardcore bosons in a zig-zag optical superlattice
, 2013 We study a system of hard-core bosons at half-filling in a one-dimensional optical superlattice. The bosons are allowed to hop to nearest and next-nearest neighbor sites producing a zig-zag geometry and we obtain the ground state phase diagram as a ...

Type II superlattices for infrared detectors and devices [PDF]
, 1991 Superlattices consisting of combinations of III-V semiconductors with type II band alignments are of interest for infrared applications because their energy gaps can be made smaller than those of any 'natural' III-V compounds.
