Organic transistors get small Researchers from Cornell University have shown that it is possible to fabricate useful organic thin film transistors that have a channel length as small as 30 nanometers. The smaller the channel, the faster the transistor. Previously, organic TFT channel lengths were limited to about 100 nm. |
