The mobility of organic semiconductors can be tuned by modifying their chemical composition or crystalline properties. Here, the authors show that bending organic single crystals increases their field effect transistor mobility due to restrained mole

Low-frequency noise generated by a fluctuation of current is a key issue for integrating electronic elements into a high-density circuit. Investigation of the noise in organic field-effect transistors is now sharing the spotlight with development of

A linear relationship between spin and momentum relaxation shows that the spin relaxation in an organic semiconductor crystal that has ultra-long spin lifetimes and coherent band-like transport is governed by the Elliott–Yafet mechanism.

Trap states, present in any semiconductor, have a large influence on charge transport as well as various other physical processes relevant for device performance. Therefore, quantifying the density of trap states (trap DOS) in a semiconductor is a cr

We report the observation of band-like transport from printed polymer thin films at room temperature. This was achieved from donor-acceptor type thiophene-thiazole copolymer that was carefully designed to enhance the planarity of the backbone and the

Dual-gated PbS nanocrystal field-effect transistors employing SiO2 and Cytop as gate dielectrics are fabricated. The obtained electron mobility (0.2 cm(2) V-1 s(-1)) and the high on/off ratio (10(5)-10(6)), show that the controlled nanocrystal assemb

Small molecular organic semiconductor crystals form interesting electronic systems of periodically arranged “charge clouds” whose mutual electronic coupling determines whether or not electronic states can be coherent over fluctuating molecules. T
