  8. Typical temperature is 800 - 1000 in cvd diamond process, while the high temperature limits its application in optical window and coating such as gaas, zns etc. low temperature can not only make diamond crystal nucleus finer, reduce surface roughness of diamond films and lessen light dispersion, but also eliminate thermal stress

    化學氣相沉積金剛石膜過程中,襯底的典型溫度為800 1000 ,這么高的溫度限制了其作為gaas 、 zns等低熔點光學材料窗口和塗層的應用。低溫沉積金剛石膜不僅可以使晶粒細化,降低表面粗糙度,減小光的散射作用,而且可以消除熱應力。
