I've found some interesting links about Compact Modeling. The first one is the homepage of Dr. Zhou Xing, at the Nanyang Technological University (Singapore). A quite interesting page, with links to many of his papers and works.
The second link is more educational, and contains the material of a course in the "Grupo de Electrónica del Estado Sólido de la Universidad Simón Bolívar" (Caracas, VENEZUELA). The only drawback of this excellent page is that it is in a mixture of Spanish and English. However, the completeness of the page fully justifies a visit.
