Progress in organic single-crystal field-effect transistors [PDF]

, 2017
Research on organic thin-film transistors tends to focus on improvements in device performance, but very little is understood about the ultimate limits of these devices, the microscopic physical mechanisms responsible for their limitations, and, more ...

Concentration-dependent mobility in organic field-effect transistors probed by infrared spectromicroscopy of the charge density profile

, 2007
We show that infrared imaging of the charge density profile in organic field-effect transistors (FETs) can probe transport characteristics which are difficult to access by conventional contact-based measurements.

Generalized Einstein relation for disordered semiconductors - implications for device performance

, 2004
The ratio between mobility and diffusion parameters is derived for a Gaussian-like density of states. This steady-state analysis is expected to be applicable to a wide range of organic materials (polymers or small molecules) as it relies on the existence

Single-Crystal Organic Charge-Transfer Interfaces probed using Schottky-Gated Heterostructures

, 2012
Organic semiconductors based on small conjugated molecules generally behave as insulators when undoped, but the hetero-interfaces of two such materials can show electrical conductivity as large as in a metal.

Improvement of the poly-3-hexylthiophene transistor performance using small molecule contact functionalization

, 2009
We demonstrate an approach to improve poly-3-hexylthiophene field effect transistors by modifying the gold contacts with monolayer thick pentacenequinone (PQ) or naphthalene (NL). The effective contact resistance is reduced by a factor of two and sixteen

Organic film thickness influence on the bias stress instability in Sexithiophene Field Effect Transistors

, 2009
In this paper, the dynamics of bias stress phenomenon in Sexithiophene (T6) Field Effect Transistors (FETs) has been investigated. T6 FETs have been fabricated by vacuum depositing films with thickness from 10 nm to 130 nm on Si/SiO2 substrates.

Low Contact Resistance Organic Single‐Crystal Transistors with Band‐Like Transport Based on 2,6‐Bis‐Phenylethynyl‐Anthracene

Advanced Science
Contact resistance has become one of the main bottlenecks that hinder further improvement of mobility and integration density of organic field‐effect transistors (OFETs).

Dual Optoelectronic Organic Field-Effect Device: Combination of Electroluminescence and Photosensitivity

Molecules
Merging the functionality of an organic field-effect transistor (OFET) with either a light emission or a photoelectric effect can increase the efficiency of displays or photosensing devices.
