Inspired by experiments on magic angle twisted bilayer graphene, we present a lattice mean-field model for the quantum anomalous Hall effect in moir\'e setting. Our hopping thus provides simple route to Chern insulator commensurately models. We study of our ribbon geometry, which demonstrate presence thick chiral edge states that have transverse localization scales with spacing. also electronic...

In recent years, graphene has received so much attention because of its superlative properties and potential to revolutionize electronics, especially in VLSI. This study analyzes the effect single-event upset (SEU) an SRAM cell, which employs a metal-oxide semiconductor type nano-ribbon field transistor (MOS-GNRFET) compares results with another cell designed using PTM 10 nm FinFET node. Our si...

We theoretically investigate the one-color injection currents and shift in zigzag graphene nanoribbons with applying a static electric field across ribbon, which breaks inversion symmetry to generate nonzero second order optical responses by dipole interaction. These two types of can be separately excited specific light polarization, circularly polarized lights for linearly currents. Based on t...

We report the realization of top-gated graphene nanoribbon field effect transistors (GNRFETs) of ~10 nm width on large-area epitaxial graphene exhibiting the opening of a band gap of ~0.14 eV. Contrary to prior observations of disordered transport and severe edge-roughness effects of GNRs, the experimental results presented here clearly show that the transport mechanism in carefully fabricated ...

Herein, the edge states in a finite-width graphene ribbon and semi-infinite geometry subject to perpendicular magnetic field an in-plane electric field, applied zigzag edge, are explored. To accomplish this, combination of analytic numerical methods within framework low-energy effective theory is employed. Both gapless gapped Dirac fermions considered. It found that surface mode localized at re...
