Title: | Low-temperature properties of thin films | Authors: | Tošić B. Šetrajčić J. Mirjanić D. Bundalo Z. |
Issue Date: | 1-Jul-1992 | Journal: | Physica A: Statistical Mechanics and its Applications | Abstract: | It is shown that phonons in this films, "cut off" from a simple lattice, possess a gap whose magnitude depends upon the thickness of the film. Due to the presence of the gap, the specific heat of the film for T≈ 0 changes approximately as T-1 exp(-const/T). This behaviour of the specific heat can be used for experimental verification of the existence of the phonon gap. © 1992. | URI: | https://open.uns.ac.rs/handle/123456789/13298 | ISSN: | 03784371 | DOI: | 10.1016/0378-4371(92)90311-D |
