Numerical coupling of electric circuits with heat flow and semiconductor models

It was launched in June 2004 as one of four partial project of  the common project "Numerical Simulation of electric circuits in the time domain"  with partners at the universities in Wuppertal, Berlin and Köln.

Within the project new models for optoelectronic semiconductor devices like laser and photo diodes based on the energy transport model have been developed. Self heating effects in devices are modelled by the heat flow equation, with a new energy conserving source term.

Moreover, the electro-thermal semiconductor models have been numerically coupled to electric and thermal network model equations and algorithms have been developed for the iterative solution of the strongly coupled systems.

The numerical results show the significant influence of heating effects in nanoscale devices and integrated circuits and show the need of thermal consideration in circuit simulation.

Coupled Multiscale Simulation and Optimization in Nanoelectronics (CoMSON)

CoMSON is a Marie Curie Research Training Network supported by the European Commission in the framework of the programme "Structuring the European Research Area" within the 6th Framework Research Programme of the European Union. It was established on October 1st, 2005, and will run for a total of four years.

In CoMSON and the "Math&Industry" project  partially the same project partners were involved. Due to the strong thematic interface a intence collaboration emerged and both projects and project partners benefit from mutual consulting and exchange of experience. Results attained in the Math&Indutry project have been implemented in the CoMSON demonstrator plattform.
