Temperature Dependence of Electrical Properties in Regioregular Poly(3-hexylthiophene) Modulated by Chemical Doping
Electrical conductivity and Seebeck coefficient in regioregular poly(3-hexylthiophene) (RR-P3HT) doped with iodine (I2) have been studied in temperature (T) range from 4.2 K to 300 K and from 77 K to 300 K, respectively. In spite of high doping rate (about 30%), RR-P3HT doped with I2 shows a semiconductive behavior in view of temperature dependence of both electrical conductivity and Seebeck co...
متن کاملOn the role of single regiodefects and polydispersity in regioregular poly(3-hexylthiophene): defect distribution, synthesis of defect-free chains, and a simple model for the determination of crystallinity.
Identifying structure formation in semicrystalline conjugated polymers is the fundamental basis to understand electronic processes in these materials. Although correlations between physical properties, structure formation, and device parameters of regioregular, semicrystalline poly(3-hexylthiophene) (P3HT) have been established, it has remained difficult to disentangle the influence of regioreg...
متن کاملHigh ambipolar and balanced carrier mobility in regioregular poly(3-hexylthiophene)
The carrier transport of carefully purified regioregular poly(3-hexylthiophene) films has been studied using time-of-flight photocurrent measurements. We find balanced ambipolar transport with a room-temperature mobility for holes of 3Ã10−4 cm2 V−1 s−1 and for electrons of 1.5Ã10−4 cm2 V−1 s−1 at electric fields ù105 V/cm. The transport is relatively field independent and weakly temperature dep...

چکیده یکی از مهمترین دغدغه های بزرگ جوامع بشری، از دیر باز تا کنون که ذهن پژوهشگران و متخصصان بهداشت روانی و اجتماعی و دولتها رابه خود مشغول داشته، مسأله ی بزهکاری می باشد. شناخت کامل پدیده ی بزهکاری و بزهکار، علل وعوامل سقوط یک انسان، چگونگی درمان وی و درنهایت پیشگیری ازبزهکاری ودریک کلام سالم سازی یک جامعه، رسالت عظیم، انسانی ومقدسی می باشد که با بررسی شخصیت مجرم یعنی[ انسانی که تحت شرای...
15 صفحه اولDependence of Regioregular Poly(3-hexylthiophene) Film Morphology and Field-Effect Mobility on Molecular Weight
Morphological characterization has been used to explain the previously observed strong correlation between charge carrier mobility measured with thin-film transistors and the number-average molecular weight (MW) of the conjugated polymer regioregular poly(3-hexylthiophene). Atomic force microscopy and X-ray diffraction show that the low-mobility, low-MW films have a highly ordered structure com...
