On the Neumann problem of one-dimensional nonlinear thermoelasticity with time-independent external forces
Asymptotic stability of stationary solutions to the drift-diffusion model in the whole space
We study the initial value problem for the drift-diffusion model arising in semiconductor device simulation and plasma physics. We show that the corresponding stationary problem in the whole space ℝ admits a unique stationary solution in a general situation. Moreover, it is proved that when ≥ 3, a unique solution to the initial value problem exists globally in time and converges to the corresponding stationary solution as time tends to infinity, provided that the amplitude of the stationary solution...
