제목 극초단 펄스 레이져를 이용한 유기 박막 양각 그레이팅 가공 ( Surface embossed grating patterning of organic thin films, using the ultrafast laser)
초록 Diverse surface embossed grating structures were fabricated on Poly (3, 4-ethylenedioxythiophene)–polystyrene sulfonic acid (PEDOT:PSS), poly (3-hexylthiophene)(P3HT) and P3HT: phenyl-C61-butyric acid methyl ester (PCBM) (P3HT:PCBM)blend films by the laser direct writing method using the femtosecond laser irradiation at 1030 nm. In case of PEDOT:PSS and P3HT:PCBM films, the photo-induced expansion were observed in accordance with different fluences of the laser. In addition, these patterns were formed into various shapes under different conditions.  The method we used to build embossed grating patterns is able to locally change a structure and property of organic layers within sub-micron sized area by laser irradiation partially. Detail analyses about the expansion were studied by AFM, X-ray, Micro raman, etc.
