Effect of driving frequency on the structure of silicon grown on Ag (111) films by very-high-frequency magnetron sputtering Project supported by the National Natural Science Foundation of China (Grant Nos. 11675118 and 11275136). |
(color online) AFM height retrace images of silicon on Ag (111) films sputtered by 60 MHz, at the powers of (a) 50 W (2D), (b) 50 W (3D) and (c) 150 W (2D), and (d) 150 W (3D). |
