Résumé :

A new 2D material, phosphorene, has several remarkable advantages; various superiorities make phosphorene a research hotspot. This paper provides comprehensive information about the structure and electronic and magnetic properties of phosphorene adsorbed with atoms, including alkali and alkaline-earth metal atoms, nonmetallic atoms, noble metal atoms, and transition-metal atoms. Phosphorene adsorbed with alkali and alkaline-earth metal atoms, such as Li and Na adatoms, becomes an n-type semiconductor, while phosphorene adsorbed with Be and Mg atoms becomes a p-type semiconductor. In view of no

Résumé :

Alkali metal (Cs/Li/Na) adsorption on (5, 5) and (9, 0) single-walled carbon nanotubes (CNTs) with a capped edge had been investigated by first-principles calculations. Our calculations are performed within density functional theory (DFT) under the generalized gradient approximation (GGA) of Perdew, Burke, and Ernzerhof (PBE).For the indefective (5, 5)/(9, 0) CNT, adsorption energy ordering of the alkali-metal adatoms is Cs>Li>Na so that the Cs adsorption was energetically favored with respect to the Li/Na adatom. However, the adsorption energy ordering of the alkali-metal adatoms for th

Résumé :

First-principles calculations were performed to study the adsorption characteristics of 15 different metal atoms on germanene. For the alkali metal adatoms (Li, Na, and K) on germanene, the bonding is approximately ideal ionic and the semimetallic germanene finally becomes metallic with a small band gap opening at the Dirac point. The bonding of alkaline earth metal atoms (Be, Mg, and Ca) to germanene is a mixture of ionic and covalent. The Be and Mg adsorptions lead to semiconducting behavior in germanene, while similar to Li, Na, and K adsorptions, the Ca adsorbed germanene is metallic. For

Résumé :

Monolayer graphene exhibits many spectacular electronic properties, with superconductivity being arguably the most notable exception. It was theoretically proposed that superconductivity might be induced by enhancing the electron–phonon coupling through the decoration of graphene with an alkali adatom superlattice [Profeta G, Calandra M, Mauri F (2012) Nat Phys 8(2):131–134]. Although experiments have shown an adatom-induced enhancement of the electron–phonon coupling, superconductivity has never been observed. Using angle-resolved photoemission spectroscopy (ARPES), we show that lithium depos

Résumé :

The study of alkali-metal adsorption on metal and semiconductor surfaces has been a favored topic of surface science. This is motivated by a number of interesting physical effects, such as charge transfer, work function changes, and alteration of surface reactivity. Despite considerable research efforts, however, there has still been significant controversies about most of these properties. In this paper, a review is presented concerning alkali–metal adsorption on well-defined transition-metal and semiconductor surfaces, with particular emphasis on the bond-nature analysis using low-energy D +
