Transparent pentacene-based photoconductor: high photoconductivity effect
In this paper, the fabrication and characterisation of pentacene-based photoconductors using indium tin oxide electrodes obtained by ion beam sputtering are discussed. The photoelectric properties of pentacene under red (632 nm) and ultraviolet (365 nm) illuminations were investigated. We have shown that the photocurrent was dependent on the wavelength, bias voltage and illumination side of the...
متن کاملPentacene-based organic transistors
This report discusses some of the electrical and optical properties of thin films of the organic semiconductor pentacene fabricated using thermal evaporation. Conductivities of between 1.84 × 10 Ω cm and 7.49 × 10 Ω cm are reported. Transistors using thermally evaporated pentacene were fabricated and mobilities of up to 0.03 cmVs were obtained.
متن کاملHigh-intensity terahertz radiation from a microstructured large-area photoconductor
We present a planar large-area photoconducting emitter for impulsive generation of terahertz sTHzd radiation. The device consists of an interdigitated electrode metal-semiconductor-metal sMSMd structure which is masked by a second metallization layer isolated from the MSM electrodes. The second layer blocks optical excitation in every second period of the MSM finger structure. Hence charge carr...
متن کاملHigh‐Performance Nonvolatile Organic Field‐Effect Transistor Memory Based on Organic Semiconductor Heterostructures of Pentacene/P13/Pentacene as Both Charge Transport and Trapping Layers
Nonvolatile organic field-effect transistor (OFET) memory devices based on pentacene/N,N'-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (P13)/pentacene trilayer organic heterostructures have been proposed. The discontinuous n-type P13 embedded in p-type pentacene layers can not only provide electrons in the semiconductor layer that facilitates electron trapping process; it also works as c...
متن کاملEffect of impurities on pentacene island nucleation
Pentacenequinone PnQ impurities have been introduced into a pentacene source material in a controlled manner to quantify the relative effects of the impurity content on the grain boundary structure and thin film nucleation. Atomic force microscopy has been employed to directly characterize by weight films grown by using 0.0%–7.5% PnQ in the source material. Analysis of the distribution of captu...
