Abstract
We have found a resonance of an alternative type in the current-voltage curve of the non-one-dimensional resonant-tunneling structure with three quantum dots. It is an exponentially narrow dip with an exponentially small minimum that appears independently of the width of the energy spectrum of incident electrons. The structure considered is the simplest two-lead structure that has such a property.
