I. Barbereau et al., PHOTOTHERMAL INVESTIGATION OF IMPLANTED SI WAFERS - INFLUENCE OF THERMAL-DIFFUSIVITY, Progress in Natural Science, 6, 1996, pp. 503-506
Implanted Si wafers are studied by two photothermal techniques in very
different experimental conditions. Photothermal microscopy is known t
o be very sensitive to implantation but modelization can be cumbersome
. Mirage detetection at low frequency is shown to be very effecient in
characterizing implanted samples even though the thermal wave length
is much greater than the damage depth. It is precisely this fact that
permits a simpler modelization.
