THERMAL STABILITY AND SPECIFIC MATERIAL PROPERTIES OF NANOSYSTEMS

Various material properties, which are well defined and clearly fixed for macroscopic systems, get a modified significance in nanophysics and nanotechnology, respectively. We show, as an example, that the temperature behavior of nanosystems is considerably changed when we go from macroscopic systems to those of nanometer size. It is pointed out that the standard model of solid-state physics (ordered structure, harmonic approximation) is in general not sufficient for the description of nanosystems.
