Welcome to the website of
Minari Group -Printed Electronics-!
National Institute for Materials Science (NIMS)
We study the physics and fabrication methods for printed electronics devices.
Printing of semiconductor devices under ambient atmospheric conditions is a promising method for large-area, low-cost fabrication of flexible electronic products. At present, however, the relatively low resolution of the printed products due to the difficulty in controlling liquid motion on the surface prevents their use in practical applications. We are therefore developing novel printing and self-assembly techniques for flexible printed electronics such as organic field-effect transistors. We are also engaged in a fundamental investigation of device physics in order to improve the performance of printed electronic products.

Research Activities
Outline
Printed electronics is a technology that allows bottom-up fabrication of electronic devices from functional inks using printing techniques. Large-scale, low-cost production of printed electronic devices is now expected because of the recent development of novel inks and printing techniques. We are pursuing the fabrication of printed electronics by developing novel patterning methods using different functional inks. In particular, we focus on organic field-effect transistors (OFETs) as key devices in next-generation flexible electronics. The physics of charge injection and transport in OFETs is also studied.
