아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 제목: Fluerenes with diversed structures and their applications 연사: 신 현 석 교수 (울산과학기술대) 일시: 2008년 12월 5일(금) 오후4:30 장소: 물리학과 세미나실(31355호실) 초록: Fullerene (C60), a highly conjugated organic molecule has been widely studied as one of the important organic semiconductors potentially applicable for integrated FET, superconductor, photodetector and photovoltaic device. In this talk, I will address the historical background of C60 and the recent trend of C60 structure-related research. Then, two research results on (I) C60 disks and (II) the spontaneous electron transfer from C60 to Au ions will be presented. (I) The highly selective synthesis of disk-shaped 2D single crystalline C60 was performed by using a vapor-solid process. The experimental results describe: 1) the substrate effect on the highly selective formation of C60 disks, 2) the structural characterization of the disks, 3) photoluminescence properties of the disks, and 4) the photoconductivity of a single disk. (II) The spontaneous electron transfer from C60 to Au ions readily converted the intrinsic majority charge carrier of semiconducting C60 from electron to hole by forming discrete Au nanoparticles. The resulting Au-C60 system showed a stable p-type field effect transistor (FET) characteristic even in ambient condition at room temperature. Another interesting feature of the hole-doped C60 FET device was the selective silencing of photocurrent at visible wavelength region. http://physics.skku.ac.kr/ppt/1205.PPT
