CSCAMM Seminar: Dr. Clemens Heitzinger - PDE Models for Nanowire Bio- and Gas Sensors including Stochastic Effects
Description:
We have developed PDE models for the quantitative understanding of nanowire bio- and gas sensors. We have also developed a new parallel algorithm for the numerical solution of the drift-diffusion-Poisson system.
In both bio- and gas sensors, several stochastic effects occur. We have obtained an existence and uniqueness result for a diffusion equation. Numerical results are compared with measurements. Furthermore, a nonlinear elliptic stochastic equation is discussed.
Using these results, we have performed simulations and have found the optimal operating regime by optimizing device parameters. Different surface models are used for gas sensors and results from their simulation are presented.
