3차원 불연속 모델을 이용하여 유기발광다이오드(OLED)의 전도 메커니즘을 제안하였다. 우리는 각 방출 분자가 인접한 분자 사이의 실제 전하 이동에 따라 호핑 사이트에 해당한다고 가정했습니다. Alq1의 캐리어 이동성과 각 캐리어의 장벽 높이 모두 실험 데이터에서 파생되었습니다. 캐리어, 필드 및 엑시톤 분포의 일시적인 동작을 계산합니다. 두 캐리어 주입 모두 쇼트키 주입을 가정했습니다. 이전 결과에서 계산된 전류밀도가 전류밀도장 곡선에서 실험값과 일치한다고 가정했을 때, 계산된 발광강도는 발광장 곡선에서 실험값과 맞지 않았다. 게다가 계산된 발광장 곡선의 기울기가 너무 작아서 실험 곡선에 맞지 않습니다. 이전 연구에서는 호핑 거리를 1.7nm로 가정했다. 본 연구에서는 XNUMX nm로 가정하였다. 우리는 전자 주입의 필드 의존성이 쇼트키 방출만을 설명하기에는 너무 약하다고 생각합니다. 전자 주입이 쇼트키 방출과 Fowler-Nordheim 방출로 가정되면 계산된 발광 필드뿐만 아니라 전류 밀도 필드 곡선도 각 실험 특성의 곡선에 맞춰졌습니다.

Abstract: We proposed the conduction mechanism of organic light-emitting diode (OLED) using a one-dimensional discontinuous model. We assumed that each emitting molecule corresponds to a hopping site according to the actual charge transfer between adjacent molecules. Both carrier mobility of Alq3 and barrier heights for each carrier were derived from experimental data. We calculate transient behavior of carrier, field, and exciton distribution. Both carrier injections assumed the Schottky injection. In the previous results, when we assumed that calculated current density fit the experimental one in the current density field curve, calculated light-emission intensity did not fit the experimental one in the light-emission field curve. Furthermore, the slope of the calculated light emission-field curve is too small to fit the experimental one. In the previous study, hopping distance was assumed to be 1 nm. In this study, it is assumed to be 1.7 nm. We consider that field dependence of electron injection is too weak to explain only the Schottky emission. When the electron injection is assumed to be both Schottky emission and Fowler-Nordheim emission calculated light-emission field as well as the current-density field curves were fit to the curve of each experimental characteristics.
