It is shown that the morphological transformation of just - percolated , 10 nm ( nominal thickness ) Au films evaporated on glass and annealed at 600 degrees C , i . e . , in the vicinity of the substrate glass transition temperature ( Tg = 557 degrees C ) , proceeds via three processes exhibiting different time scales : ( i ) fast recrystallization and dewetting , leading to formation of single - crystalline islands ( minutes ) ; the initial spectrum characteristic of a continuous Au film is transformed to that of an island film , displaying a surface plasmon ( SP ) absorption band .
