“…A possible way of distinguishing among these effects is the use of photoacoustic techniques ͑PA͒, in particular by investigating the PA dependence on the modulated chopping frequency of the incident light beam f. These techniques are versatile, nondestructive, and can be employed under different experimental conditions for determining thermal parameters of solid materials. Several photoacoustic cells with slight modifications, [5][6][7][8] including the derivative photopyroelectric 8,9 and photothermal deflection 10 methods, have been used in some special cases with great success. [11][12][13] The apparatus for all techniques is basically the same, the modifications being mainly concentrated on the type of detector and on its location relative to the sample inside the cell.…”

“…These applications are very versatile, ranging from thermal diffusivity [4][5][6][7] and thermal effusivity [8] measurements to detection of X-rays [2], characterization of heterostructure component materials [9], and in vivo and in situ studies in plant photosynthesis research [10].…”
