Abstract
A quantum effect switching device comprising a substrate 12, first and second tunnel barriers 14 and 18, and a quantum well 16. The current between a drain region 20 and the substrate 12 can be switched by placing a potential on a gate layer 24. The potential on the gate layer 24 selectively modulates the effective dimensions of the quantum well 16 to alter the allowed energy levels within the conduction band of the quantum well 16.
