Zusammenfassung, Abstract
Rapid nonthermal melting can occur under the action of a supershort laser pulse in semiconductors. An attractive method for quantitatively describing the kinetics of such effects can be molecular-dynamic modelling, in which the interatomic potential depends on the parameters of the excited carriers. This paper discusses the properties that such a potential must possess. Based on a simple model for photoexcited carriers, it is shown that the condition of conservation of energy imposes definite requirements on the potential. (C) 2014 Optical Society of America.
