| Abstract: |
| In this paper, we study the weak solutions to stationary bipolar quantum driftdifiusion model for semiconductors in one space dimension. The model is reformulated as two coupled fourth-order elliptic equations by using exponential variable transformations. The existence of weak solutions to the reformulated equations is proved by using Schauder flxed-point theorem. Furthermore, the uniqueness of solutions and the semiclassical limit to the equations are obtained. |
