Structure and electronic transport in graphene wrinkles.
Calculations of the energetics explain the morphological transition and indicate that the tall ripples are collapsed into narrow standing wrinkles by van der Waals forces, analogous to large-diameter nanotubes, consistent with transport simulations.
Electronic transport and device prospects of monolayer molybdenum disulphide grown by chemical vapour deposition.
The electronic transport and device properties of monolayer molybdenum disulphide grown by chemical vapour deposition are reported and it is revealed that these devices have the potential to suppress short channel effects and have high critical breakdown electric field.
Graphene plasmonics for terahertz to mid-infrared applications.
The basic properties of graphene plasmons are reviewed: their energy dispersion, localization and propagation, plasmon-phonon hybridization, lifetimes and damping pathways, and emerging and potential applications.
Multi-terminal transport measurements of MoS2 using a van der Waals heterostructure device platform.
Modelling of potential scattering sources and quantum lifetime analysis indicate that a combination of short-range and long-range interfacial scattering limits the low-temperature mobility of MoS2.
Photoconductivity of biased graphene
Scientists report that the photovoltaic effect and a photo-induced bolometric effect, rather than thermoelectric effects, dominate the photoresponse during a classic photoconductivity experiment in
Damping pathways of mid-infrared plasmons in graphene nanostructures
Researchers clarify damping pathways for mid-infrared graphene plasmons, including graphene intrinsic optical phonons and edge scattering. They also demonstrate the guiding of mid-infrared graphene
Conductance Asymmetry of Graphene p-n Junction
We use the nonequilibrium Green function method in the ballistic limit to provide a quantitative description of the conductance of graphene p-n junctions - an important building block for graphene
Tunable Light-Matter Interaction and the Role of Hyperbolicity in Graphene-hBN System.
It is found that the graphene plasmon couples differently with the phonons of the two Reststrahlen bands, owing to their different hyperbolicity, which leads to distinctively different interaction between an external quantum emitter and the plAsmon-phonon modes in the two bands.
Mobility anisotropy in monolayer black phosphorus due to scattering by charged impurities
We study the charged impurity limited mobility in black phosphorus, a highly anisotropic layered material. We compute the mobility within the Boltzmann transport equation under detailed balance
Room-temperature high spin–orbit torque due to quantum confinement in sputtered BixSe(1–x) films
Sputtered BixSe(1–x) thin films can generate very large current-induced spin–orbit torque, capable to switch both in-plane and out-of-plane magnetized CoFeB-based structures deposited on top, at room temperature.
