Abstract
In the framework of scattering theory and in terms of the notion of local partial density of states(LPDOS), we derived the expressions of the linear and the second order nonlinear emittance, which is the imaginary part of admittance, for the quantum dot structure. With the help of discrete Hamiltonian model we obtained the linear and the second nonlinear partial density of states. By using the linear and the nonlinear emittance we could obtain expressions which can be used to detect the density of state(DOS) of the sample.
