Abstract

We present the results of the investigations carried out on the effect of ultrasonic vibration of the substrate during deposition and during aging on the instabilities of island silver films deposited on glass held at room temperature in a vacuum of 2 × 10-6 Torr. The films which are vibrated only during deposition aged slower than unvibrated films and vibration during aging enhances the aging. The occurrence of Large Scale Coalescence (LSC) is studied by repeated deposition technique. LSC occurs at a lower deposition number for films vibrated during deposition, whereas it does so at a higher deposition number for films vibrated during aging. The results of these studies strongly support the applicability of mobility coalescence theory in explaining aging in metal island films.
