아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시부터 2층 라운지세미나실에 다과를 준비하오니 많은 참석 부탁드립니다 아 래 제목: Enhanced emission rate from a single quantum well using surface plasmon 연사: 이 장 원 박사(삼성종합기술원) 일시: 2009년 4월 3일(금) 오후4:30 장소: 물리학과 세미나실(31355호실) 초록: Recently, light emitting diode (LED) has gained great attention due to its energy efficiency and form factor. In this talk, structure of LED will be briefly introduced and how to enhance the emission rate will be discussed. I will focus on the enhancement of the internal quantum efficiency by using resonant surface plasmon coupling. The key idea is to use increased density of states of the surface plasmons introduced by metal deposition. Conditions for resonant coupling will also be discussed. After brief introduction to the physical principles, our experimental results with theoretical predictions will be presented. 66174481676617448167
