The data of the article “Transport of electron hopping regulated by the geometric configuration of quantum-dot arrays”

This dataset is derived from the numerical simulation study of electronic transport characteristics of silicon-based circular quantum dot arrays. The generation and processing process is as follows: Firstly, based on the constructed universal Fermi Hubbard model, the geometric characteristics and three transition modes (nearest neighbor NNH, next nearest neighbor NNNH, long-range LRH) of the circular array are characterized by the effective Euclidean distance matrix D (describing the distance between quantum dots) and adjacency matrix A (describing the transition path), respectively; Subsequently, the exact diagonalization method was used to solve the extended Hubbard Hamiltonian matrix, obtaining the energy eigenvalues of the multibody system, and then calculating the electron addition energy; Finally, combining linear response theory with the Fermi Dirac distribution, calculate the quantum conductivity spectra under different parameters. During the processing, MATLAB is used for matrix operations and diagonalization to achieve the drawing of energy spectrum and conductivity spectrum curves. The data in the dataset has been classified according to the images in the article and packaged in folders. The files in the folder are named according to the simulation parameters (corresponding to the image numbers).
