Time spectroscopy of a film bolometric response to mm-waves power as a method of the thermodynamic coefficients diagnostics in a film structures

Abstract

We have applied 4 and 8 mm band wave power for a pulse heating of the film and investigated a time function of a film overheating temperature with a help of time and temperature dependencies of a film electrical resistivity (R) [l]. The time function of R(t) is recorded by our equipment in a computer memory with a different size of a time scales. For a submicron thickness films we have neglected by film temperature gradient which can E 0 n: c d 1 2 3 t , m s
