Learners enrolled: 933
Materials display properties. What is the physics behind these properties? Starting from an electronic or atomic level, how can we arrive at the properties of the materials? These are the questions this course will attempt to answer. Focus will be on electronic properties, but other properties will also be looked at.

INTENDED AUDIENCE :  Any interested Learners
PRE-REQUISITES :  First Year under graduate level of physics and mathematics will be beneficial but is not absolutely necessary.
Course Status : Completed
Course Type : Core
