OFETs based on new solution-processed ester functionalized 9,10-ter-anthrylene-ethynylenes show a mobility increase of four orders of magnitude, leading to mobilities as high as 4.9 Ã 10â2 cm2 Vâ1sâ1 if the deposited film is annealed before contact deposition. The behavior is ascribed to an increase in film order at the dielectric/semiconductor interface as revealed by X-ray studies.
基于新溶剂加工的酯功能化9,10-四并芘乙炔的有机场效应晶体管显示出四个数量级的迁移率提升,如果在接触沉积前对沉积膜进行退火处理,迁移率可高达4.9 × 10^-2 cm^2 V^-1 s^-1。这种行为归因于介电层/半导体界面处薄膜有序性的增加,这一点已通过X射线研究得以揭示。
