M. Sumetskii, EXPONENTIALLY NARROW CURRENT DIP FOR RESONANT-TUNNELING STRUCTURE OF 3 QUANTUM DOTS, Physical review. B, Condensed matter, 48(19), 1993, pp. 14288-14290
We have found a resonance of an alternative type in the current-voltag
e curve of the non-one-dimensional resonant-tunneling structure with t
hree quantum dots. It is an exponentially narrow dip with an exponenti
ally small minimum that appears independently of the width of the ener
gy spectrum of incident electrons. The structure considered is the sim
plest two-lead structure that has such a property.
