FIG. 1.

(a) Schematic of the photovoltaic wire-dot-wire junction submitted to a bias voltage . (b) Basic principles of the Green's function technique in the description of one-particle properties in a nano-junction.

FIG. 2.

(a) Band diagram of the unbiased two-dot junction: discrete energy levels are available in the dot chain at eV and eV. We used the same interdot coupling strength for the conduction band and the valence band: eV (see text for the other parameters). (b) Discrete energy levels of the two coupled dots hybridize in the dot molecule picture at eV, eV, eV, and eV. Three types of transitions are thus involved: A, B (two fold by CB/VB symmetry), and C, for increasing energy values.

Left current as a function of the photon energy for V. The curve shows three resonance peaks at (A), 1.489 (B), and 1.689 eV (C).

Plot of the left current in arbitrary units (logarithmic scale) as a function of the photon energy and the bias voltage.

Left current as a function of the bias voltage for maximal resonance under bias, (A), 1.488 (B), and 1.690 eV (C).
