Наслов: | HIGH-FREQUENCY ACOUSTIC PHENOMENON IN QUASI-TWO-DIMENSIONAL ORGANIC CONDUCTORS | Authors: | KRSTOVSKA, DANICA GALBOVA, OLGA |
Issue Date: | 20-ное-2008 | Publisher: | World Scientific Pub Co Pte Lt | Journal: | International Journal of Modern Physics B | Abstract: | <jats:p> The propagation of a monochromatic high-frequency longitudinal acoustic wave along the normal to the layer (z-axis) in a bulk quasi-two-dimensional conductor (Q2D), in the absence of an external magnetic field under assumption of arbitrary scattering of the charge carriers from the boundary surface, is studied theoretically. The effect of the Q2D electron energy spectrum features on the attenuation of an ordinary acoustic wave (OAW) and of an anomalous acoustic wave (AAW) is discussed. It is shown that for certain values of the characteristic parameters, the OAW in Q2D is strongly attenuated, and the asymptotic form of the acoustic field in the conductor is determined by the AAW. In the case of a Q2D conductor, the anomalous acoustic field is transmitted by electrons belonging to the belt points of the Fermi surface. </jats:p> | URI: | http://hdl.handle.net/20.500.12188/8007 | DOI: | 10.1142/s0217979208049352 |
