По выбранной ортогональной последовательности полиномов $\{p_n(s)\}_{n=0}^{\infty}$, которая имеет дискретный спектр, строится энергетический спектр $E_k=f(s_k)$, где $\{s_k\}$ - точки конечного или бесконечного дискретного спектра полиномов. С помощью подхода к квантовой механике, который основан не на функциях потенциала, а ортогональных полиномах, зависящих от энергии, построена локальная чи...

 In this paper, we study the electronic conductance and density of states for a comb-like polymer with periodic hopping energies in the tight-binding approach. Electron transmission coefficient and density of states are analytically calculated by using Green’s function of the system. The results show that the electronic conductance spectrum has one energy gap in the absence of carbon-hydrogen b...
