Abstract
A new resistance resonance effect based on the quantum-mechanical delocalization of electrons in a symmetric-double-well potential is presented. We show that changing the symmetry of the potential profile gives rise to a resistance peak if the transport properties of the two wells are different. The proposed effect is demonstrated experimentally in semiconductor heterostructures.Keywords
