Unexpected short- and medium-range atomic structure of sputtered amorphous silicon upon thermal annealing
We investigate the structure of magnetron-sputtered (MS) amorphous silicon(a-Si) prepared under standard deposition conditions and compare this to pure ion-implanted (II) a-Si. The structure of both films is characterized in their as-prepared and thermally annealed states. Significant differences are observed in short- and medium-range order following thermal annealing. Whereas II a-Si undergoes structural relaxation toward a continuous random network, MS a-Si exhibits little change....[Show more]
