We report a lithographic approach to pattern multiple types of Layer-by-Layer self-assembled nanoparticle thin films. 150 nm and 64 nm polystyrene particles are separated in desired patterns with a feature size 5 to 20 microns. The process is quite simple, consisting of only two consecutive lift-offs, and there is no high requirement for the equipments.(More)
In this article, we report the fabrication of organic field-effect transistors using self-assembled SiO2 as a gate dielectric material and pentacene as a semiconductor. The dielectric layer was self-assembled with 10 layers of SiO2 nanoparticles 45 nm in diameter, and its breakdown field was larger than 0.57 MV/cm. Being a low-cost and low-temperature(More)
Pentacene organic field-effect transistors (OFETs) were fabricated and investigated with thermal oxide and a self-assembled SiO/sub 2/ (SA-SiO/sub 2/) nanoparticle thin-film as the gate dielectrics. SA-SiO/sub 2/ film functions well as a gate dielectric with a breakdown field larger than 0.57 MV/cm and leakage current less than 2 nA/mm/sup 2/ with an(More)
