Several amorphic carbon films with different thickness were deposited on single crystal silicon by means of pulse laser ablating graphet target at room temprature.
Magnesium oxide thin films on Y-cut lithium niobate single crystal substrate are prepared by sol-gel processing then,a Mg-ion indiffusion process is applied to study its surface characteristics.
Based on the result of theoretical research the absorption coefficient curve of a substrate material has be ound,which ensure the three-channel BCCD work in the region of X-ray.
