Electron wave coupling or decoupling devices and quantum interference devices. |
摘要 |
<p>Novel electron wave combining and/or branching devices and Aharonov-Bohm type quantum interference devices are proposed, which have no curved electron waveguide structures to form an electron branching or decoupling part or ring geometry. But instead the electron branching part or ring geometry is effectively constructed in a straight double quantum well structures, by the control of the shapes of the wave functions or of the subband energy levels relative to the Fermi level by electric fields. <IMAGE></p> |
