We study the effect of Landau-Zener (LZ) tunneling caused by the varying sweeping rate of external field, formulating and approximately solving the problem with many levels of the LZ tunneling rate. Comparing with the steadily vary about sweeping fie

According to the tight-binding approximation, we investigate the electronic structures of graphene ribbons with zigzag shaped edges (ZGRs) and armchair shaped edges (AGRs) drawn by the tensile force, and obtain the analytic relations between the ener

The hybrid orbitals of carbon atoms in the D6h C36 molecule are studied using two rotating ellipsoid models. The model 1 is 1.66R for the short semi-axis and 2.34R for the long semi-axis, and the model 2 is 1.78R and 2.26R respectively, where R is th

The extended Wannier function constructed by hydrogen-like atom wave function is used to calculate the electronic hopping and the density of the states of trans-polyacetylene with a single-chain planar structure. In this technique 2s and 2pz orbitals

The Wannier function method used in a stable lattice is extended to calculate one-electron Hamiltonian matrix elements in polyacetylene. In this technique only a2Pz orbital of the electrons is taken into account and the matrix elements are given anal

Graphene is the name given to a flat monolayer of carbon atoms tightly packed into a twodimensional honeycomb lattice (Novoselov et al., 2004), and is a rapidly rising star on the horizon of materials science and condensed matter physics. This two-di

We study the effect of Landau–Zener (LZ) tunneling caused by the varying sweeping rate of the external field, and solve the problem about the LZ tunneling rate among many levels. The LZ tunneling rate is essentially changed by the unsteady variatio
