乾轉移石墨烯電極鈣鈦礦量子點塔米共振腔發光二極體之研究

Abstract

Tamm plasma RCLED是一種將塔米電漿(Tamm plasmon)結構應用於共振腔發光二極體(Resonant Cavity Light Emitting Diode, RCLED)中的發光元件。通過在共振腔中引入塔米電漿結構，可以改變光的發射特性和增強發光效率。本篇論文藉由設計布拉格反射鏡(Distributed Bragg mirror, DBR)和金屬反射鏡形成共振模態波段為530nm的共振腔發光二極體。利用塔米電漿由金屬層和介電質層之間形成的強電場區域進行高效率的光電轉換，當金屬和單層石墨烯作為電極施加電壓時，載子會在主動層鈣鈦礦量子點中進行複合並產生發光，也因塔米電漿的微腔結構可以將發光的光子反射回共振腔中，增強光子的循環和調製從而大大提升發光的效率。

Tamm plasma RCLED is a light-emitting device that incorporates Tamm plasmon structures into a Resonant Cavity Light Emitting Diode (RCLED). By introducing Tamm plasmon structures within the resonant cavity, the emission characteristics of light can be modified and the overall light emission efficiency can be enhanced. In this paper, a resonant cavity with a wavelength band of 530nm was designed using Distributed Bragg mirrors (DBRs) and metal reflectors. The strong electric field region formed between the metal layer and dielectric layer, through Tamm plasmons, enables efficient optoelectronic conversion. When a voltage is applied to the electrodes using metal and monolayer graphene, carriers undergo recombination in the active layer of perovskite quantum dots, resulting in light emission. Additionally, the microcavity structure of Tamm plasmons reflects emitted photons back into the resonant cavity, enhancing photon circulation and modulation, thus significantly improving the efficiency of light emission.
