Some words on the Workshop’s concentration thema:

Prática de Surf na praia da JoaquinaThe drift diffusion equations are the most widely used model to describe semiconductor devices. From the point of view of applications, there is great interest in replacing laboratory testing by numerical simulation in order to minimize development costs. For the current state of technology, the drift diffusion equations represent a realistic compromise between computational efficiency (to solve this nonlinear system of partial differential equations) and an accurate description of the underlying device physics.
Avenida Beira Mar NorteThe name drift diffusion equations of semiconductors originates from the type of dependence of the current densities on the carrier densities and the electric field. The current densities are the sums of drift terms and diffusion terms. It is worth mentioning that, with the increased miniaturization of semiconductor devices, one comes closer and closer to the limits of validity of the drift diffusion equation. This is justified, on the one hand, by the fact that in ever smaller devices the assumption that the free carriers can be modeled as a continuum becomes invalid. On the Fortaleza de Anhatomirimother hand, the drift diffusion equations are derived through a limit process, where the mean free path of a particle tends to zero.
The mathematical modeling of semiconductor equations has developed significantly, together with their manufacturing. The basic semiconductor device equations where first presented, in the actual level of completeness, by W. Van Roosbroeck in 1950. Since then they have been subject of intensive mathematical and numerical investigation
