Characteristic time of thermal and diffusion relaxation

© O.V. Aryasova, Y.M. Khazan, 2015

It is shown that frequently used dimensional estimate of a layer thermal relaxation time, , as L2/ based on the layer thickness, L, and thermal diffusivity, , strongly overestimates . The correct estimate should contain a factor of which is of the order of 0.1.

Key words: characteristic time, thermal relaxation.
