Electronics - New transistor on the block
Nano-transistors 10 times smaller than conventional ones and being developed at ORNL could change the complexion of the electronics industry. Transistors, which can be used as amplifiers, detectors or switches, are integral parts of computers, telephones and virtually all electronic components. Traditional transistors are based on single energy barriers that electrons either tunnel through or attain sufficient energies to overcome. The electron device being developed at ORNL is based on multiple energy barriers, resulting in an effective energy barrier that can be either raised or lowered, thereby modulating electron flow. The device is also potentially much faster than a conventional transistor.
