Adsorption Of Methane

The adsorption of methane (CH4) molecule on the pristine and Al-doped (4, 8) graphene was investigated via the first-principles calculations. The results demonstrated that, in comparison to the adsorption of a CH4molecule on the pristine graphene sheet, a relatively stronger adsorption was observed between the CH4molecule and Al-doped graphene with a shorter adsorption distance, larger binding energy and more charge-transfer from the graphene surface to the CH4molecule. Therefore, the Al-doped graphene can be expected to be a novel sensor for the detection of CH4molecules in future applications.

To enhance the wettability between Ag atoms and graphene of graphene-reinforced silver-based composite filler, the adsorption behavior of Ag atoms on graphene was studied by first-principles calculation. This was based on band structure analysis, both p-type doping and n-type doping form, of the vacancy-defected and Ce-doped graphene. It was verified by the subsequent investigation on the density of states. According to the charge transfer calculation, p-type doping can promote the electron transport ability between Ag atoms and graphene. The adsorption energy and population analysis show that both defect and Ce doping can improve the wettability and stability of the Ag-graphene system. Seen from these theoretical calculations, this study provides useful guidance for the preparation of Ag-graphene composite fillers.

Donor Acceptor

Based on nonequilibrium Green’s function and first-principles calculation, we investigate the transport properties of the molecule device with a donor-acceptor molecular complex sandwiched between two electrodes. Numerical results show that a negative differential resistance under applied bias can be observed. The mechanism of negative differential resistance is mainly induced by the orbital match of molecule and electrodes as well as intermolecular charge transfer.

Effective Charge Transfer

The improvement of the arsine adsorption on monolayer MoS2 by doping has been investigated by first-principles calculation. The impurity atoms Si, P, and Cl, have been introduced to substitute S atoms to form an [Formula: see text]- or [Formula: see text]-type system. The electronic properties of MoS2 with dopants P and Cl are insensitive to the adsorption of AsH3. The Si-MoS2 with adsorbed AsH3 configuration has the largest adsorption energy, the lowest adsorbed height, and the most effective charge transfer. It is indicated that the properties of MoS2 can be improved by doping for detecting AsH3 molecules.
