摘要:
The transport of a sheet of excess carriers in a conducting material having two types of mobile carriers is described in a small‐signal approximation. It is shown that the carriers exhibit an equivalent diffusion in the drift direction due to the dielectric relaxation effect even in the absence of thermal diffusion, and that the total effective diffusion coefficient is given by the sum of the thermal diffusion coefficient and the two‐carrier diffusion coefficient.
