We mainly study the analyticity and decay rates of global solutions for a class of fractional drift-diffusion system. The system is a generalization of the classical Poisson-Nernst-Planck equations in semiconductor devices, which mathematically exhibits the mixed partial differential equations by the fractional nonlinear parabolic equations coupled with the second-order elliptic equations. By using multilinear singular integral theories and the Fourier localization argument, we show that the global-in-time solutions are Gevrey analytical in critical Besov spaces. As a corollary, we also obtain temporal decay rates of this global solutions.
