摘要
报道了VO2薄膜在TEACO2激光照射下的相变特性的实验研究。结果表明:对于本文镀制的VO2薄膜,在偏置温度为52°C条件下,TEACO2激光入射能量密度为150mJ/cm2时,可使VO2薄膜发生相变。响应时间<50ns,恢复时间≈200μs。
This paper reports the experemental study of phase transition properties of VO 2 films in irradiation of TEA CO 2 laser. The experemental results show that at biasing temperature 52°C, incident fluence of 150 mJ/cm 2 for TEA CO 2 laser phase transition can be occured from semiconductor state to metal state for our VO 2 films. Response time <50 ns, restoration time≈200 μs.
