Original Abstract

Scanning thermal microscopy (SThM) belongs to the large family of scanning probe microscopy (SPM), where the main principle is based on measurement a certain physical property in different points of a sample surface. In the context of SThM the desired property in ideal case would be the coefficient of thermal conductivity, but it cannot be measured directly. The tip consists of very thin wollaston wire half-loop and it is possible to measure only the current flowing while a certain voltage is applied. These two information (voltage and current) should be recalculated to thermal conductivity of the sample. This article describes how to simulate the heat flow using open source programs.
