Td. Bennett et al., SEPARATING THERMAL, ELECTRONIC, AND TOPOGRAPHIC EFFECTS IN PULSED-LASER MELTING AND SPUTTERING OF GOLD, Physical review letters, 76(10), 1996, pp. 1659-1662
An attempt was made to separate thermal from electronic effects during
laser sputtering of gold by partitioning the target surface energy be
tween steady-state electron beam heating and pulsed laser heating. For
flat starting surfaces and a peak surface temperature of similar to 2
700 K, the Au translational energy remains (2-3)X higher than classica
l expectations and is insensitive to how energy is partitioned between
steady-state heating and laser heating. The mean desorption energy is
linearly dependent on peak surface temperature, but with a slope of 1
5k(B)T as opposed to the classical 2k(B)T.
