Study on Surface Modification of Indium Tin Oxide and Resist Surfaces Using CF₄/O₂ Plasma for Manufacturing Organic Light-Emitting Diodes by Inkjet Printing

Abstract

The paper describes experiments on a metal ball rolled along parallel metal rails. An electrical force is developed on the ball in the direction of movement by passing current through it from one rail to the other. Contrary to the electromagnetic theory of the ball-bearing motor, the electrical force on a brass ball is of the same order as that on a steel ball. The results are discussed in terms of a torque exerted in the contact region.

Multi-color microfluidic organic light-emitting diodes based on on-demand emitting layers of pyrene-based liquid organic semiconductors with fluorescent guest dopants

“…4(a) and (b), respectively. The untreated ITO (sample A) consists of three different carbon environments at 284.6 eV for C C, at 286.2 eV for C O (ethers and/or epoxy), and at 288.6 eV for O C O (esters) [39]. From the C 1s spectrum of the GOPTS-SAM-treated ITO (sample C), increase in C O bonds was observed, which are attributed to epoxy functionality in chemical structure of GOPTS-SAM (see also Supplementary Fig.…”

Flexible Nonstick Replica Mold for Transfer Printing of Ag Ink

“…4 5 Printing technologies are thus envisaged to pave the way for frontier flexible electronics, such as flexible displays, sensors, and radio frequency identification cards. [6][7][8] Among various printing methods, the basic concepts of nano-imprint lithography and transfer printing are widely adapted to the transfer of all the components, i.e., metal electrodes, insulators, and semiconductors, needed to fabricate thin-film transistors (TFTs) on a plastic substrate. For examples, Menard et al reported bendable TFTs fabricated by transferring free standing micro-structured * Authors to whom correspondence should be addressed.…”

“…As mold precursors, acrylic mixtures were prepared from silsesquioxane-based materials, silicone acrylate, poly(propylene glycol) diacrylate, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl methacrylate, and photoinitiator. By using these materials, the replica molds were fabricated from a silicon master onto a flexible substrate by means of UV-assisted molding process at room temperature.…”

Self‐Organization of Inkjet‐Printed Organic Semiconductor Films Prepared in Inkjet‐Etched Microwells

“…The pattern accuracy may be increased by steering the ink spreading using local patterns on the substrate surface. One approach involves prepatterning banks of insulator materials onto the substrate to concentrate the ink into defined areas 6, 7. Prepatterning processes, however, have unfortunately presented an obstacle to the production of large‐area displays: prepatterning processes rely on conventional photolithographic techniques that are complicated and relatively costly.…”
