Carrier concentration dependence of the mobility in organic semiconductors
Charge transport in organic materials as a function of carrier concentration is investigated. An analytical model of the concentration dependent obility based on the variable hopping range theory is formulated. This model is applied to analyze the discrepancy between the experimental obilities extracted from FETs and LEDs. The result shows that an exponential density of states (DOS) is a good a...

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولImpact of doping on the density of states and the mobility in organic semiconductors
We experimentally investigated conductivity and mobility of poly(3-hexylthiophene) (P3HT) doped with tetrafluorotetracyanoquinodimethane (F 4 TCNQ) for various relative doping concentrations ranging from ultralow (10 −5) to high (10 −1) and various active layer thicknesses. Although the measured conductivity monotonously increases with increasing doping concentration, the mobilities decrease, i...
متن کاملAccurate and simultaneous determination of carrier density and mobility in organic semiconducting materials
How to accurately determine carrier mobility and density in organic semiconducting materials is a very important subject for their optoelectronic applications including light-emitting diodes, solar cells, and thin film field-effect transistors. In this work, we report on a unique data analysis procedure for space-charge limited currents to simultaneously obtain the carrier density and mobility ...
