In this course, the learners will understand fundamental basic backgrounds of p-n junctions, diodes and MOSFETs (Metal Oxide Semiconductor Field Effect Transistors). Also, recent approaches on flexible / stretchable electronics, transparent optoelectronics, and printed electronics using one dimensional or two dimensional nanomaterials will be introduced. Furthermore, the formation of high-performance, transparent thin films or conductors using novel materials such as cellulose nanofibers or metal nanofibers is included for course materials. Examples of device fabrications, including touch screen panels, gas / chemical / bio sensors, smart contact lenses, wireless and transparent antennas, and OLEDs, are also introduced for next generation electronic devices.
