Thermal training of functional surfaces fabricated with femtosecond laser pulses

The effect of thermal training of a functional surface fabricated by means of femtosecond laser surface processing on a crystalline silicon (c-Si) surface is found for the first time. Hydrodynamic and thermal properties of the c-Si surface are revealed to be considerably modified by femtosecond laser processing and follow-up thermal training. The carried out experimental studies of wetting, evaporation, and boiling processes on the thermal trained laser processed surface open up ample opportunities in creation of tailored functional surfaces for micro/optoelectronic devices and power engineering applications.
