概要

• 論文の詳細を見る

• The absorption and emission spectra of single-electron transistors are theoretically studied by the Keldysh Green function method. We calculate the electronic levels and Coulomb interactions of the electrons of InAs quantum dots (QDs) using the effective mass model. It is found that Coulomb interaction and level mixing in the many-body open system lead to double peaks associated with the intraband transitions involving the two lowest levels of the QDs.
