Witryna18 paź 2013 · The impurity states are quasilocalized states caused by the disorder [ 16 ]. The injected electron will be reflected when its energy is equal to the energy level of the quasilocalized states; indeed quasilocalized states in disordered graphene near Dirac points have been observed experimentally and numerically [ 17 ].
WitrynaThe localization of electrons in the field of isolated nonmagnetic impurity atoms on the surface of a nanotube is considered. A model of a Gaussian separable impurity potential capable of localizing an electron at any intensity is used. The positions of the local level are found. The positions of the resonances are found, their widths are ...
