Tamm resonances and minibands in the models of atomic chains and superlattices
The spectrum of the modelled regular superlattice which includes contacts is investigated using the transfer-matrix formalism. It is shown that the separated pair resonances in the chain spectrum (which are distributed in the permitted and in the forbidden zones, respectively) appear due to the ex...

Показано, що існування одного контакту призводить до виникнення відокремлених парних резонансів у спектрі ланцюжка, а також продемонстровано розмиття таких резонансів у відповідні мінізони після поєднання окремих регулярних сегментів у супергратку.

| description |
The spectrum of the modelled regular superlattice which includes contacts
is investigated using the transfer-matrix formalism. It is shown that the separated pair resonances in the chain spectrum (which are distributed in the
permitted and in the forbidden zones, respectively) appear due to the existence of a single contact. The eroding of the noted minizones after making
correlations between the separate regular segments in the superlattice is
demonstrated. Similar resonances and minizones which can be called the
Tamm resonances and minizones are considered to be useful elements
for describing the surface states and zone-band structure of real systems
within the restricted geometry. |
