Silicon Nanocrystal Superlattices [PDF]

open access: yesChemPhysChem, 2012
Colloidal nanocrystals with precisely controlled size and shape can be assembled into ordered superlattices.[1–3] Superlattices have been made of a wide range of materials, from semiconductors to metals to insulators, and have been explored for various applications, including sensors,[4–6] transistors,[7,8] data storage,[9] solar cells,[10] and ...

Magnetoplasmons in layered graphene structures [PDF]

open access: yes, 2008
We calculate the dispersion equations for magnetoplasmons in a single layer, a pair of parallel layers, a graphite bilayer and a superlattice of graphene layers in a perpendicular magnetic field.

A Theoretical Simulation of the Radiation Responses of Si, Ge, and Si/Ge Superlattice to Low-Energy Irradiation

open access: yesNanoscale Research Letters, 2018
In this study, the low-energy radiation responses of Si, Ge, and Si/Ge superlattice are investigated by an ab initio molecular dynamics method and the origins of their different radiation behaviors are explored.

Superior Electrocatalytic Activity of MoS2-Graphene as Superlattice

open access: yesNanomaterials, 2020
Evidence by selected area diffraction patterns shows the successful preparation of large area (cm × cm) MoS2/graphene heterojunctions in coincidence of the MoS2 and graphene hexagons (superlattice).

Influence of quantum dot shape on energy spectra of three-dimensional quantum dots superlattices

open access: yesФізика і хімія твердого тіла, 2020
The band spectrum of quantum dots superlattices of different shapes at points of high symmetry is determined. Cubic, cylindrical and spherical quantum dots are considered. The width of the minizone is calculated.

Effect of the strain on spin-valley transport properties in MoS2 superlattice

open access: yesScientific Reports, 2021
The effect of the strain on the spin and valley dependent transport properties, including the conductance and polarization, through a monolayer MoS2 superlattice under Rashba spin–orbit coupling is theoretically investigated.

Quasiadiabatic dynamics of ultracold bosonic atoms in a one-dimensional optical superlattice [PDF]

open access: yes, 2015
We study the quasiadiabatic dynamics of a one-dimensional system of ultracold bosonic atoms loaded in an optical superlattice. Focusing on a slow linear variation in time of the superlattice potential, the system is driven from a conventional Mott ...

Diffraction from Nanocrystal Superlattices

open access: yesNanomaterials, 2022
Diffraction from a lattice of periodically spaced crystals is a topic of current interest because of the great development of self-organised superlattices (SL) of nanocrystals (NC). The self-organisation of NC into SL has theoretical interest, but especially a rich application prospect, as the coherent organisation has large effects on a wide range of ...

Investigation of switching region in superlattice phase change memories

open access: yesAIP Advances, 2016
We investigated superlattice phase change memories (PCMs) to clarify which regions were responsible for switching. We observed atomic structures in a superlattice PCM film with a stack of GeTe / Sb2Te3 layers using atomically resolved EDX maps, and we ...
