A theoretical ideal two-dimensional electron gas (2DEG) was characterized by a flat density
of states independent of energy. Compared with conventional two-dimensional free-electron …

Nanopatterns at near atomic dimensions with controllable quantum dot states (QDSs) are
promising candidates for the continued downscaling of electronic devices. Herein, we report …

Electrons confined within the 2D layer of metals grown on silicon substrates exhibit exotic
properties due to strong correlation effects. The properties, such as the 2D …

Bismuthene is a promising large-gap two-dimensional topological material with potential
applications in quantum devices. However, fabricating a stable bismuthene on a substrate …

We investigate the Bi on Si (111) 3× 3 β-phase surface reconstruction using scanning
tunneling microscopy. Details of the bias-dependent images of both the reconstruction and …

Density functional theory calculations have been performed to investigate the structural and
electronic properties of the Pb@ germanene adsorption system. By employing equilibrium …

Semiconductors interfaced with heavy elements possessing a strong atomic spin–orbit
coupling are important building blocks for the development of new spintronic devices. Here …

This report investigates the adsorption of monolayers of X (Tl, Pb, Bi) at silicene and the
dynamical stability of the system. Based on the density functional theory calculations it is …

Abstract The Bi/Si (111) surface reconstruction is an attractive two-dimensional (2D) surface
phase due to its compatibility with current Si-based electronic industry and due to its …

The hydrogenation of two-dimensional (2D) systems can efficiently modify the physical and
chemical properties of materials. Here we report a systematic study on the hydrogenation of …
