摘要：

We present a novel method for calculating electronic properties of large and complex systems based on a local density approximation by using a combination of Chebyshev polynomial expansion and time-dependent method. The electron density is obtained without calculating eigenenergies and eigenstates with the computational time which scales as O(N). This method is applied to calculate the electronic structure of a model n-type GaAs quantum dots.
