The First Paper-Based Transistors

Roland Piquepaille found news of research out of Portugal that has resulted in the first paper-based transistors (the original article is less informative than Roland's blog). More precisely, they've made the first field effect transistors (FET) with a paper interstrate layer. According to the research team, such transistors offer the same level of performance as 'state-of-the-art, oxide-based thin film transistors produced on glass or crystalline silicon substrates.' Possible applications include disposable electronics devices, such as paper displays, smart labels, bio-applications or RFID tags. The research will be published in IEEE Electron Device Letters in September.

Not paper transistors dammit

The INTERSTRATE layer is paper now. In a normal FET, the whole thing has a doped silicon substrate functioning as the grid and body, with a (say) metal oxide semiconductor in between as an insulator (interstrate) (MOSFET). They replaced the MOS with paper. It's still a hunk of silicon.

Coming soon, the 5 MHz toilet paper.

Overclock it to 10Mhz for extra warmth on those cold winter mornings...

This is great and everything....

but this will put even more demand on forests and the farming of trees - they grow too slow to keep up with the potential demand of these products (Just think of how many electronic devices are made and you know that disposable ones are going to sell like hotcakes!).

What they really need to do is use something very common; like, I don't know, sand. That's assuming they can come up with the technology. I know, I know. I'm dreaming.
