Query: 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.
