We did an analysis of the contents in the subject named “solid state physics” at District University and, we found that these contents have been kept in an invariant scheme in front of new developments and research in this field, such as the physics of new materials. For example, today the improvement of new alloys such as NITINOL, which needs to be characterized, is being studied to know its properties and its advantages over other existing materials. Therefore we propose to introduce this topic in the course mentioned.
