Scanning tunnelling microscopy on organic field-effect transistors based on intrinsic pentacene

Pentacene-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.

Degradation of organic field-effect transistors made of pentacene

This article reports degradation experiments on organic thin film transistors using the small organic molecule pentacene as the semiconducting material. Starting with degradation inert p-type silicon wafers as the substrate and SiO2 as the gate dielectric, we show the influence of temperature and exposure to ambient air on the charge carrier field-effect mobility, on-off-ratio, and threshold-vo...

Organic field-effect transistors based on tetrathiafulvalene derivatives*

In recent years, tetrathiafulvalene (TTF) and its derivatives have been used as semiconducting materials for organic field-effect transistors (OFETs). In this review, we summarize the recent progress in the field of TTF-based OFETs. We introduce the structure and operation of OFETs, and focus on TTF derivatives used in OFETs. TTF derivatives used in OFETs can be divided into three parts by the ...

Organic Field-Effect Transistors

Organic field-effect transistors (OFETs) were first described in 1987. Their characteristics have undergone spectacular improvements during the last two or three years. At the same time, several models have been developed to rationalize their operating mode. In this review, we examine the performance of OFETs as revealed by recently published data, mainly in terms of field-effect mobility and o...
