Question

compare: tight binding and zone theory​

Answer 1

Answer:

the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site.

Answer 2

Answer:

Tight binding

In solid-state physics, the tight-binding model is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method used in chemistry.

Zone thorey

A theory of urban land-use patterns, developed by William Burgess, that states that a city will assume the form of five concentric urban zones: the central business district, the zone in transition, the zone of working persons' homes, the zone of better residences, and the commuters' zone.
