    Competence
    Knowledge of the basic properties and models of crystalline solids.
    Teaching methodology
    Lessons five hours per week, covering both theory and problems (in a 3-to-1 proportion, approximately). An experimental part (i.e., laboratory lessons) is not included in this course: In the University of Santiago de Compostela, that corresponds to another course ("Técnicas Experimentais Avanzadas", in the next year in the career of Physics). The Solid State Physics part corresponds to 1/3 (i.e., 30 hours) of that course.

    Assessment system
    The final qualification comes from the classwork and the result of one written examination at the end of the course.
    Study time and individual work
    One hour per each teacher lesson (theory or problems).
    Recommendations for the study of the subject
    Be at the teachers' lessons. Try to solve the homework suggested by the teachers (problems and questions). Use the bibliography.
