We investigate the thermoelectric properties of a hybrid nanodevice composed two-dimensional carbon-based material and superconductor. This system presents nonlinear bipolar thermoelectricity, as induced by spontaneous breaking particle-hole (PH) symmetry in tunnel junction between bilayer graphene (BLG) Bardeen-Cooper-Schrieffer In this scheme, effect, predicted observed superconductor-insulat...

Abstract The development of scalable techniques to make two-dimensional (2D) material heterostructures is a major obstacle that needs be overcome before these materials can implemented in device technologies. Electrodeposition an industrially compatible deposition technique offers unique advantages scaling 2D heterostructures. In this work, we demonstrate the electrodeposition atomic layers WS ...

Electrostatic ~gated! quantum dots are studied by computational methods. Electronic properties of the electrostatic quantum dots are determined by the confinement potential, which is created by external voltages, applied to the electrodes, and band offsets. We have solved the Poisson equation for the two-terminal quantum dot nanodevice made of several GaAs and AlGaAs layers and obtained the con...

One-dimensional (1D) carbon nanotubes (CNTs) and 2D single-atomic layer graphene have superior thermal, electrical, and mechanical properties. However, these nanomaterials exhibit poor out-of-plane properties due to the weak van der Waals interaction in the transverse direction between graphitic layers. Recent theoretical studies indicate that rationally designed 3D architectures could have des...

We demonstrate theoretically and experimentally a high extinction ratio and compact size TE-pass polarizer made by a D-shaped fiber coated with a double graphene/PMMA stack. The light propagating in the core of the fiber can be efficiently coupled into the graphene sheet thanks to the giant enhancement of the modal evanescent field associated with the high refractive index graphene/PMMA claddin...

Due to the excellent electronic, optical, thermal, chemical, and mechanical properties of graphene, it has been applied in microdevices and nanodevices. However, there are some structural defects in graphene limiting its application in micro electromechanical systems (MEMS). These structural defects are inevitable during processing, and it is difficult to assess their effect on the micro/nano d...

A terahertz (THz) fiber is of interest due to low loss and easy beam shaping. Graphene plays an important role in modulating the optical signal. In this paper, a graphene-coated D-shaped THz modulator proposed. The performance proposed investigated by finite element method. inference geometric parameters structure on also analyzed, optimal obtained. Simulation results show that confinement full...

We investigate by means of molecular dynamics simulations stretch-induced stepwise translocation of single-stranded DNA (ssDNA) through graphene nanopores. The intrinsic stepwise DNA motion, found to be largely independent of size and shape of the graphene nanopore, is brought about through alternating conformational changes between spontaneous adhesion of DNA bases to the rim of the graphene n...
