Functionalization of [Formula: see text] monolayer doped by the transition-metal Fe adatom [Formula: see text]–[Formula: see text] and NO absorption on [Formula: see text]–[Formula: see text] has been investigated computationally using first-principles calculations based on the density functional theory. We found that the system of [Formula: see text]–[Formula: see text] remains a semiconductor, with spin polarization at the Fermi level. However, for the system with absorption of NO molecule on the surface of [Formula: see text]–[Formula: see text] monolayer, its spin polarization is turned over at the Femi level, which provides a promising material for spintronic sensors.

The density functional theory calculations are applied for C20 cage fullerenes. Furan, pyrole, and phenylvinyle monomers are made to interact with a C20 cage at the same C position. An electric field was applied with varying strength. Computations were carried out for all cases at the B3LYP/6-31G* level. The structure, energetic, and relative stabilities of the compounds were compared with each other and analyzed. In addition, the electric field dependent and independent electronic transition spectra of the proposed stable neutral C20 cage are investigated.

We present first-principles calculations of the structural, electronic and magnetic properties of Gd-doped [Formula: see text] based on the density functional theory within [Formula: see text] schemes. It is found that Gd atom favors substituting for Al site. Compared with undoped [Formula: see text], the Gd-doped [Formula: see text] has become an indirect band gap semiconductor of reduced band gap. The magnetic moment [Formula: see text] per molecule mainly comes from Gd ion with little contribution from the Ga, Al and N atoms. It is confirmed that the ferromagnetic configuration is stable for [Formula: see text]. It is found also that there is hybridization between the forbital of the Gd atom and the [Formula: see text] orbital of the N atom.

The adsorption of Cl on the γ-TiAl (100) surface is studied by using the first-principles calculations based on the density-functional theory. The calculated result show that the most stable site for Cl adsorption is the four-fold-hollow site denoted by HFa. The binding energy per Cl atom increases when the coverage is more than 0.75ML. The Cl atoms are more likely to interact with the Ti atoms than the Al atoms from not only the electronic structure but also the atomic structure.

The present study deals with first-principles calculations of the thermal properties of ZnTe in the two phases namely, zinc-blende and wurtzite. The calculations are mainly performed using the density functional theory with the local density approximation and response-function calculations. The full phonon dispersions throughout the Brillouin zone are presented. The temperature dependence of the lattice parameters, bulk modulus, entropy and heat capacity are examined and discussed. Our findings agree reasonably well with those available in the literature.
