Popis: | Quantum size effects in thin semimetallic Bi films can manifest themselves in the form of a semimetal—semiconductor transition occurring under decreasing Bi layer thickness. A model of a semimetal—semiconductor transition, which takes into account a significant difference in electron and hole effective masses in Bi and the presence of the surface acceptor states is proposed. Using the proposed model, a more accurate interpretation of the experimental results is given. |
