摘要: | 本研究提出了一個新穎的雙電極光電晶體結構之概念。藉由結合電阻式隨機存取記憶體與有機體異質接面太陽能電池的功能整合形成垂直式串疊結構來實現光電晶體的行為與效應。有機太陽能電池能夠有效地吸收光能量並且產生光電流,而電阻式隨機存取記憶體則扮演了電阻大小可切換的電阻器。與典型的光電晶體相比,我們全新的設計具有幾個吸引人的特性,其中包含超快的光響應時間、可調製的光電流輸出以及溶液製成的主動層。上述所說的光電流輸出及電阻式隨機存取記憶體狀態切換等行為只需要兩個垂直夾層式電極便能夠實現,而這是有利於高速光通信、電路微型化與節省能源消耗的。不僅如此,這種新穎的光電晶體結構具有其獨特的邏輯特性,使其在光通訊的應用中具有很大的潛力。 This study presents a novel concept of an organic two-terminal phototransistor structure. The transistor effect is realized by the functional integration of a resistive random access memory and an organic bulk heterojunction solar cell forming a tandem structure. The organic solar cell efficiently harvests photon energy and generates photocurrent, and the RRAM acts as a switchable resistor. Compared with conventional phototransistors, our new design possesses several intriguing features, including ultra-fast photoresponse time, controllable photocurrent, and all solution processes for the active layers. Most importantly, all the above features (i.e. photocurrent output and switching of RRAM state) are achieved with only two vertically sandwiched electrodes, which is beneficial for high speed optical communication, circuit miniaturization, and energy saving. In addition, its unique logical characteristics have a great potential to be implemented into optical communication with a wide variety of application. |
