Taking into account the equilibrium of mechanical equilibrium, the theory of perturbation of the form of the tensile heterogeneity "quantum dot-matrix" was developed. Within the framework of the deformation potential model, taking into account the perturbation of the surface of the quantum dot, the influence of the inhomogeneously deformed heterogeneity of the "quantum dot matrix" on the quantum states of charges localized inside the quantum dot is theoretically analyzed.

We investigate the Fano line shape in electron transport through a quantum dot in presence of dephasing. The dephasing effect is introduced by the Büttiker model. We derive a generalized Fano formula for the conductance that includes the components of the standard Fano line shape and the Breit–Wigner line shape. According to this formula the Fano parameter |q| decreases when the dephasing strength increases by increasing the temperature. The increase of the half width of the resonance peak by increasing the temperature measured by Zacharia et al. [Phys. Rev.B64, 155311 (2001)] which is more rapid than expected from the ordinary theories is possibly attributed to the dephasing.
