Abstract

Surface states are studied in dependence on thickness of organic quantum wells within the nearest layer approximation. It is shown that there is a material-dependent critical thickness. Structures that have thickness thinner or thicker than the critical one, exhibit qualitatively different characteristics of surface states. Criteria for existence and sign rules for location of energy levels of surface states are established which are general and contain the results of the previous works as particular cases.
