Abstract

본 논문에서는 UV 나노임프린트 공정으로 제작한 나노 콘 형태의 구조물 위에 은 나노 입자를 증착하여 광 증폭용 구조 형태를 제작하고자 하였다. 은 나노 입자의 증착은 하부 기판 표면의 젖음 특성에 따른 액적의 증발 거동을 이용하였으며, 기판 하부 열에너지의 차이에 따라서 액적 중심부부터 가장자리까지 증착 형태가 변화함을 확인하였다. 제작한 구조 형태와 유사한 구조를 시간영역 유한차분(FDTD)법을 통해 광 특성을 예측하여, 최종적으로 제작한 구조의 은 나노 입자 부근에 에너지가 집중되는 결과를 확인하였다.
In this study, we deposited silver nanoparticles on the nanocone array structure which was fabricated by the UV nanoimprint process for optical signal amplification. The deposition of the silver nanoparticles was based on the evaporation behavior of the solution droplet according to wettability of surface and the deposition pattern changed from the center of the droplet to the edge depending on the difference of thermal energy. The optical property of silver nanoparticles that were deposited on imprinted nanohole patterns was simulated by the Finite difference time domain (FDTD) analysis method, and it was confirmed that energy was concentrated around the silver nanoparticle of the finally fabricated structure.
