Abstract
The organic transistor has become more and more active in recent years due to its advantages such as lower cost, simplicity in process, flexibility and high uniformity in large area which can hardly be found in the silicon transistor. This thesis will restrict transistors (space-charge-limited transistor, SCLT) components for internal process improvement space charge, so SCLT with high switching characteristics, high output current, high stability, high repeatability and low-cost liquid processes. Although SCLT can obtain astonishing switch ability when working as top-injection device . But in order to drive organic light-emitting diodes (Organic Light Emitting Diode, OLED), must let SCLT element overall output current, increasing the switching characteristics. Elements of the past in order to increase the output current using self-assembled monolayer (Self-Assembled Monolayer, SAM) to handle the space-charge-limited transistor (SCLT) vertical nano porous channels, significantly increasing the output current; This thesis is based on the UV Ozone to process light nano porous base element and the base version (base electrode), the degree of improvement of the insulation element, and to enhance the success of the output current density to SCLT 10mA/cm2 ratio characteristic and high switching transistor105, this method also has the advantages of low cost, process simplicity and good degree of stability.
