Bc. Li et Sy. Zhang, THE EFFECT OF INTERFACE RESISTANCES ON THERMAL-WAVE PROPAGATION IN MULTILAYERED SAMPLES, Journal of physics. D, Applied physics, 30(10), 1997, pp. 1447-1454
In this paper a rigorous three-dimensional theoretical model describin
g the temperature distribution in multi-layered samples, heated by an
intensity-modulated Gaussian laser beam, is presented. The thermal int
erface resistances and the thermal conductivity anisotropy of one of t
he layers are taken into consideration. The three-dimensional thermal
diffusion model is used to investigate the effect of thermal interface
resistances on thermal conduction in three-layered samples, which is
monitored in terms of the dependences of the amplitude and phase of th
e surface temperature rise of the sample on the modulation frequency o
f the excitation beam. The theoretical results can be used as a means
of quantitative interpretation for the determination of interfacial th
ermal resistances in layered materials with modulated photothermal tec
hniques. A direct comparison between the one- and three-dimensional th
eoretical models for thermal conduction in layered materials is also p
resented.
