Abstract：The necessity of introducing the concept of local density of states for electrons into semiconductor physics to truly catch and properly express the density-of-states function at any point of a non-box or even an arbitrarily shaped irregular heterostructure is declared. And, by virtue of a novel and interesting idea, a method to establish the above-mentioned local density-of-states functions based on the density-of-states functions in box structures is proposed.This work should be of importance for the completization of the theory of electron-states architectures in semiconductor heterostructures. .
