Laser Ultrasound Methods for Investigation of Thermal Properties of Semiconductors Plate with Modified Surface Layer

摘要

In the article the results of analyze of laser ultrasound generation in inhomogeneous semiconductorsudplate is presented. The case of strong absorption of electromagnetic fields is considered. It is shown that inudthis case submicron surface layer thermal properties influence on thermal distribution evolution. The caseudof thin infinite plate considered. Peculiarities of excitation and propagation of elastic waves in such mediaudregarding gives the possibility to obtain dispersive equation for laser ultrasound wave-vectors. It is shownudthat such processes in 1D case can be described.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35156
