Controlling the Crystal Size of Organic Semiconductors
Recently, solution-processable organic semiconductors are being highlighted for their potential application in printed electronics, becoming a feasible technique to fabricate large-area flexible thin film at a low cost. The field-effect mobility of small-molecule organic semiconductors is dependent on the crystallinity, crystal orientation, and crystal size. A variety of solution-based coating techniques, such as ink-jet printing, […]
Lens-Free OLEDs with Efficiency Comparable to That of Inorganic LEDs
The use of organic light-emitting diodes (OLEDs) has extended to various applications, but their efficiency is still lagging behind inorganic light-emitting diodes. In this research, a KAIST team provided a systematic way to yield OLEDs with an external quantum efficiency (EQE) greater than 50 percent with an external scattering medium. Having properties suitable for thin […]
Spray Coated Tactile Sensor on a 3D Surface for Robotic Skin
