A method of manufacturing an amorphous carbon thin film is provided. The method includes the following steps: providing a substrate in a reaction chamber; flowing a precursor and a carrier gas into the reaction chamber; and performing a PECVD method to deposit the amorphous carbon thin film on the substrate. Wherein, the precursor includes a compound having a C&#x2261;N functional group.

Amorphous carbon thin film, manufacturing method thereof and optical system including the same

A simple method is developed in the present invention for fabricating periodic ripple microstructures on the surface of an ITO film by using single-beam femtosecond laser pulses. The periodic ripple microstructures composed of self-organized nanodots can be directly fabricated through the irradiation of the femtosecond laser, without scanning. The ripple spacing of &#x2dc;800 nm, &#x2dc;400 nm and &#x2dc;200 nm observed in the periodic ripple microstructures can be attributed to the interference between the incident light and the scattering light of the femtosecond laser from the surface of the ITO film. In the present invention, the self-organized dots are formed by the constructive interference formed in the surface of the ITO film, where includes higher energy to break the In&#x2014;O and Sn&#x2014;O bonds and then form the In&#x2014;In bonds. Therefore, the dots have higher surface current greater than other disconstructive regions of the ITO film.
