Toward Plastic Spin Transistors: Ultrafast Computers And Electronics On The Horizon?

Physicists successfully controlled an electrical current using the "spin" within electrons -- a step toward building an organic "spin transistor": A plastic semiconductor switch for future ultrafast computers and electronics. The study also suggests it will be more difficult than thought to make highly efficient light-emitting diodes using organic materials. The findings hint such LEDs would convert no more than 25 percent of electricity into light rather than heat.
