Transparent Transistors Printed On Paper

MTorrice writes "To make light-weight, inexpensive electronics using renewable materials, scientists have turned to a technology that is almost 2,000 years old: paper. Researchers fabricated organic transistors on a transparent, exceptionally smooth type of paper called nanopaper. This material has cellulose fibers that are only 10 nm in diameter. The nanopaper transistors are about 84% transparent, and their performance decreases only slightly when bent."

Is it Green or is it Transparent?

The nanopaper transistor also showed excellent optical transmittance up to 83.5%. The device configuration can be applied to many other semiconductor materials toward flexible green electronics.

This is confusing. Is it green or is it transparent? Maybe it's a light green. Just make up your mind.

Yes. Thank you for all coming today. I have here, in my hand, a new type of transistor that I have printed on this ORDINARY piece of paper. ...
What?
Of course you cant see them - they're transparent. ...
Do they work? Of course they do, and Jimmy here has a nice computer simulation of the process. ...
No, of course we can't demonstrate on the real thing, we still have to work out the interconnects and external interface, but trust me - they're on here. ...
Yes, I have printed what is essentially invisible transistors on this paper, and it will change the world. I just need a few million dollars in funding to help me work out some of the critical issues.
