%0 Journal Article %T Mathematical aspects of hydrodynamic models for semiconductors device simulation %A Armando Majorana %A Giovanni Russo %J Le Matematiche %D 1991 %I University of Catania %X Two thermodynamic models of semiconductor device are considered. The first one takes into account thermal and collisional effects, while neglecting viscous terms, which are included in the second. A qualitative analysis of stationary one-dimensional solutions is performed and some numerical results are presented. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/617
