英文摘要 | Fluorinated and hydrogenated amorphous carbon (a-C:H:F) films with increasing fluorine content are deposited using a pulsed direct current plasma enhanced chemical vapor deposition technique. The fluorine atomic concentrations of films deposited under CF4/CH4 gas with flow ratios of 2:1, 4:1, 5:1, 6:1 and 10:1 are 4.8%, 5.9%, 6.8%, 12.1% and 15.5%, respectively. As the F content increases, XPS analysis indicates that the C–C bonding structure transforms to form C–CF, C–F and –CF2 groups. TEM images show that the microstructures of the films with lower fluorine contents are constituted by many discontinuous graphite-like and fullerene-like fragments. However, features like interlocking pores and amorphousness strongly prevail in the structures when the proportion of fluorine incorporated into the films increases. The slight increase in ID/IG and the up-shift of the G peak obtained from the Raman spectrum indicate the relative increase of the sp2 configuration and the formation of sp2-hybridized carbon domains. A deposition mechanism is given to explain the microstructure evolution of the a-C:H:F films upon increasing the fluorine content. |
