# Solid State Physics

## Objectives

**Objectives**

It is intended to focus the fundamental concepts of Solid State Physics, emphasizing in the applications to engineering and life problem systematization and solving. In practical laboratory classes, it is intended to verify and prove fundamental properties of Solid State Physics, as well as the understanding of experimental setups, the systematization of data collecting and treatment of experimental results, as also the elaboration of experimental work reports.
