Overview

This course covers a set of laboratory experiments of solid state physics that contribute to the student's understanding of the composition of solids and theories related to it, such as the magnetic retardation curve experiment, the magnetic response of a homogeneous material, X-ray diffraction, the crystal structure, and the Hall effect.

Intended learning outcomes

At the end of this course the student will be able to:1- Draw the magnetic retardation curve.2- Determine the value of the energy gap.3- Determine the Hall potential, Hall constant and energy density.4- Calculate conductivity and mobility.5- Explain the experiment of determining the crystal structure of some materials using X-rays.

Teaching and learning methods

1- Short lectures.

2- Discussion and follow-up during the lab.

Methods of assessments

  1. Laboratory and theory midterm exam 25%
  2. Lab reports 25%
