Abstract

The spontaneous emission spectrum in the optically excited single-electron-tunneling device coupled to the side dot is analytically found to be determined by the 12 exciton-complex optical channels with different optical weight functions. The electronic tunneling channels and optical transition channels co-determine the emission, where the competition between the electron-like and hole-like channels leads to the tail effect and the competition between the lower and higher energy resonant optical channels leads to the blueshift (redshift) of the emission signal.
