Abstract The growth of two-dimensional hexagonal aluminum nitride (h-AlN) on transition metal dichalcogenide (TMD) monolayers exhibits superior uniformity and smoothness compared to HfO $$_{2}$$ 2 on silicon substrate. This makes an h-AlN monolayer a

Abstract This study examines the operational parameters of field-effect transistors (FETs) using single-gate (SG) and double-gate (DG) graphene nanoribbons (GNRs) within the analog/RF domain. A detailed exploration is conducted through an atomistic p

Abstract Generating fully spin‐polarized currents (FSPC) and pure spin currents (PSC) are of great importance for spintronics. Half‐metallic ferromagnets, which generate 100% spin polarization, are considered as one of the most promising material

Two-dimensional (2D) heterostructures open the door toward novel applications, such as multiterminal transistors, by integrating the properties of the participant materials. Here we construct 2D heterostars from zigzag-triangular graphene (ZTG) and g

Based on density functional theory (DFT) and non-equilibrium Green's function (NEGF) method, we studied the electron transport properties of van der Waals heterostructures (vdWHs) composed by (n,0) single-walled carbon nanotubes (SWCNTs) (n = 5–11)

Terahertz (THz) field pulses can now be applied in scanning tunneling microscopy (THz-STM) junction experiments to study time-resolved dynamics. The relatively slow pulse compared to the typical electronic time-scale calls for approximations based on

Abstract In this paper, an in silico proof of concept of a spinristor is proposed and provided; a new electronic component that combines a spin‐filter and a memristor in a single molecule, useful for in‐memory processing. It builds on the idea of
