| 概要 | We consider the initial value problem
for the drift-diffusion equation
arising in a semiconductor-devise simulations.
This equation is a coupling system of the semilinear parabolic
equation and the Poisson equation.
For the initial value problem for the drift-diffusion equation,
the well-posedness, the time-global existence
and the decay of solutions are known.
We study the large-time behavior of solutions
to the drift-diffusion equation. |
