Název v původním jazyce

Thermal stability of black aluminum films and growth of aluminum nanowires from mechanical defects on the film surface during annealing

Popis výsledku v původním jazyce

The thermal stability of black aluminum (Black Al) films deposited on unheated fused silica substrates by pulsed DC magnetron sputtering is investigated. The deposited films have porous moth-eye morphology and a relatively soft surface that can be easily damaged mechanically. Photothermally stimulated exoelectron emission (PTSE) spectra of the films have emission peaks at 180 and 300 C, which can be associated with processes of aluminum recrystallization occurring at these temperatures. The total emitted charge of PTSE decreases according to a power law with each subsequent heating, indicating that the most pronounced structural changes on the film surface occur during its first annealing. The shape of the mechanically intact pores of the films does not change after heating.
