摘要

The fabrication, physical and electrochemical properties of copper silicon alloy film were systematically studied and the optimized preparation conditions were obtained. When KrF excimer laser (λ=248 nm) repetition rate is l0Hz, laser energy is 260mJ, vacuum is 10~(-5)Pa, target and substrate revolution per minute of target is 10, substrate temperature is 300℃ and deposition time is l.0h, as-deposited film from Si target and Cu substrate is obtained by pulsed laser deposition. XRD pattern showed that as-deposited film is cubic structure of Cu_9Si, SEM images showed that as-deposited film has regular surface, particle size is about 300nm and particle size distribution is in narrow range. And the same time the electrochemical properties of as-deposited film showed good cycleability.
