• /cm2 in a sample of 1 cm2 area) and the specific heat of silicon (710 J/kg∙K), we expected the target temperature to be at ≈500 K at the end of the irradiation [39]. The radiation and the heat conduction losses were not considered in the calculation. The diffusivity (D) of Pt in silicon at 500 K is ≈3

• combination is 846/ion (TRIM calculations). Using the thermal properties of silicon (a specific heat of 710 J/kg∙K and a thermal conductivity of 150 W/m∙K) and electronic energy deposited by the ions in silicon, we expect a spike temperature of about ≈2540 K (within 1 ps and 1 nm away from the ion track) [44

• coupling factor (g) is given as [9] where De is the thermal diffusivity and Ce is the specific heat of the electronic system, λ is the mean free path of the excited electrons of the target. In the case of metals g is weak compared to insulators such as silica [40]. When a bulk metal is irradiated with SHI

In analogous to fs pulses there is an intensity regime where the nanostructures are removed by the laser irradiation without causing major damage on the Si substrate surface. The removal

• . The average sample weights of approximately 15.0–17.5 mg were placed in the aluminium crucible. Heating rates of 20 °C min−1 were used in the temperature range 20–400 °C. The crystallinity (Tc) and melting temperature (Tm) were recorded as the inflection point of the increment of specific heat and as
