Inkjet Printing of High Performance Transistors with Micron Order Chemically Set Gaps

Abstract This paper reports a 100% inkjet printed transistor with a short channel of approximately 1 µm with an operating speed up to 18.21 GHz. Printed electronics are a burgeoning area in electronics development, but are often stymied by the large minimum feature size. To combat this, techniques w...
