Controlling the Microstructure of Polymeric Semiconductors and Investigating its Effect on Charge Transport

摘要

Printed flexible electronics are a potentially disruptive technology, by enabling the pervasive introduction of electronic devices in our everyday life. From the materials standpoint, the main challenge of flexible electronics is the ability to deposit and process at low temperatures and with high throughput semiconductor layers having satisfactory performance. Polymeric semiconductors are a very promising and versatile materials family and they are well-suited for flexible electronics. These materials dissolve in common organic solvents and can be processed from a liquid solution at room temperature. Such solutions can be deposited and patterned using low-cost technologies such as inkjet, gravure or offset printing. Since their discovery, fundamental studies of the chemistry and physics of these materials have abounded. The much scarcer studies that include their microstructure often fail to paint a meaningful picture of how they work.
