描述了两种非单晶高迁移率单层发光场效应晶体管(LEFET)，它们具有窄紫外光和深蓝光发射。有机半导体是基于[1]苯并[3，2-b][1]苯并噻吩基的有机半导体，其载流子迁移率分别为2和6cm2 V−1 S−1。BTBT-C10作为LEFET的优良半导体材料在常规异质结LEFET中具有广泛的适用性。在这里，它作为蓝色、黄色和红色有机发光材料下面的薄电荷载流子层。这种布局将发射层的光学和电学特性提高了几个数量级。这两种设备架构都让位于新的显示技术和潜在的注入激光。
Two non‐single‐crystal high‐mobility single‐layer light‐emitting field‐effect transistors (LEFETs) exhibiting narrow UV and deep‐blue emission are described. The organic semiconductors are based on a [1]benzothieno[3,2‐b][1]benzothiophene (BTBT) scaffold and achieve charge carrier mobilities of 2 and 6 cm2 V−1 s−1, respectively. The general applicability of BTBT‐C10 as an excellent semiconductor for LEFETs is then demonstrated in conventional heterostructure LEFETs. Here it acts as a thin charge carrier layer underneath blue, yellow, and red organic light‐emitting materials. This layout increases the emissive layers' optical and electrical characteristics by several orders of magnitude. Both device architectures give way toward novel display technologies and potentially injection lasers.
