Abstract
Investigation of nanostructures characteristic features is one of today's important research areas in condensed state physics. Nanostructures include thin films on a substrate. The importance of these researches results from the rapid development of microelectronics and nanotechnologies. The discontinuous heating method proved to be very effective in investigation of thermal properties of a thin film on a substrate. We provided calculations for amplitude and phase of temperature oscillation in a 1 thin film with steeply decreasing thermal conductivity in the proximity to the border with substrate. We also examined the case which arises from ferroelectric phase transition analysis. It was shown that it is possible to avoid any noticeable influence of a thin film heterogeneity on the measuring results with decrease of the temperature gradient in it.Download
