| Research Abstract |
The mechanism of recrystallisation observed at room temperature in electrodeposited films has been examined in light of the enhancement of metal atom diffusion by hydrogen induced superabundant vacancies. Thermal desorption spectroscopy revealed that the films electrodeposited showed a pronounced peak, which was ascribed to the break-up of vacancy. hydrogen clusters. The grain size of the films increased as hydrogen desorption proceeded. These results indicate that the room temperature recrystallisation of electrodeposited films is caused by hydrogen induced superabundant vacancies.
