Tīmeklis2024. gada 24. jūn. · Conductance was calculated for trapezoidal nanowires with different forms and strengths of imperfection using kwant, a quantum transport software package that uses a tight-binding model. In this thesis it is found that increasing magnitudes of different imperfections such as surface charge and roughness … Tīmeklis2024. gada 1. sept. · The Kwant package finds the scattered wave function by solving a linear equation obtained from the tight-binding model. As a result, the calculation speed is faster than the lattice Green function approach. For the details of Kwant, readers are referred to the Kwant paper [35] and the manual in the Kwant website. To find the …
