Organic Electronics Picks Up the Pace: Mask‐Less, Solution Processed Organic Transistors Operating at 160 MHz
Organic printed electronics has proven its potential as an essential enabler for applications related to healthcare, entertainment, energy, and distributed intelligent objects. The possibility of exploiting solution‐based and direct‐writing production schemes further boosts the benefits offered by such technology, facilitating the implementation of cheap, conformable, bio‐compatible electronic applications. The result shown in this work challenges the widespread assumption that such class of electronic devices is relegated to low‐frequency operation, owing to the limited charge mobility of the materials and to the low spatial resolution achievable with conventional printing techniques. Here, it is shown that solution‐processed and direct‐written organic field‐effect transistors can be carefully designed and fabricated so to achieve a maximum transition frequency of 160 MHz, unlocking an operational range that was not available before for organics. Such range was believed to be only accessible with more performing classes of semiconductor materials and/or more expensive fabrication schemes. The present achievement opens a route for cost‐ and energy‐efficient manufacturability of flexible and conformable electronics with wireless‐communication capabilities.
