The First Paper-Based Transistors

kdawson posted more than 6 years ago | from the bend-me-shape-me dept.

Technology 177

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.

Batman (-1, Offtopic)

Anonymous Coward | more than 6 years ago | (#24295061)

Asia Ferguson waited. The lights above him blinked and sparked out of the air. There were coasters in the park. He didn't see them, but had expected them now for years. His warnings to Dad were not listenend to and now it was too late. Far too late for now, anyway.
Asia was a hat wearing nigga for fourteen years. When he was young he watched the coasters and he said to dad "I want to be on the coasters daddy."
Dad said "No! You will BE KILL BY COASTERS"
There was a time when he believed him. Then as he got oldered he stopped. But now in the park at the base of the coaster he knew there were coasters.
"This is DAD" the radio crackered. "You must fight the coasters!"
So Asia gotted his hat and climbed up the wall.
"HE GOING TO KILL US" said the coasters
"I will shoot at him" said the coaster and he fired the a line of cars. Asia nigged at him and tried to blew him up. But then the ceiling fell and they were trapped and not able to kill.
"No! I must kill the coasters" he shouted
The radio said "No, Asia. You are batman"
And then Asia was dead.

Honestly? It's so hard to tell sarcasm on text only forums... If you really don't get it, and want it explained, please feel free to reply.

Here's a tidbit though for those who agree with you and honestly don't get this joke (are there any such souls on /.?):

Hz is cycles per second, more or less (some will argue that this is not what Hz is - go with this) so if you had TP that moved back and forth at five times per second, what would that mean for you? If you then underclocked it by a factor of ten, you would get a half a stroke per second, which is a little more suitable for the purpose of TP.

Okay, now that I feel like an arse for explaining a joke on /., I hope I didn't really fall for one of the lesser known classic blunders... Queue Wallace Shawn (aka Vizzinni for those who don't know ... losers) jokes here: 5 4 3 2

bluefoxlucid (723572) | more than 6 years ago | (#24295203)

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.

SleptThroughClass (1127287) | more than 6 years ago | (#24295911)

Re:Not paper transistors dammit (0)

Anonymous Coward | more than 6 years ago | (#24296271)

???

The insulator is not a semiconductor, and it's not a metal oxide either. It it typically SiO2 (silicone dioxide) which is grown during fabrication.

Re:Not paper transistors dammit (1, Informative)

Anonymous Coward | more than 6 years ago | (#24297037)

Actually, what they have substituted is not the MOS, but just the O (for Oxide, i.e. Silicon Oxide, which acts as an electric insulator). The M (metal) and S (semiconductor) remain there.

So, yes, it's still mostly silicon.
