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
Core for Materials Science and Engineering.
Elective for others. Higher Semester UG and
PG students of all degree programs can benefit.
PRE-REQUISITES: First Year under graduate level of physics and mathematics will be beneficial but is not absolutely necessary.
740 students have enrolled already!!
COURSE INSTRUCTOR
Prof. Prathap Haridoss
has been a faculty in the Department of Metallurgical and Materials
Engineering, IIT Madras, since 2001. He has a B.Tech in Metallurgical
Engineering from IIT Madras, and a PhD in Materials Science from the
University of Wisconsin-Madison, USA. Before joining IIT Madras as
faculty, he worked as a Senior Scientist at Plug Power a Fuel cell
company in Latham New York. He has published papers in the areas of
Carbon nanomaterials, Fuel Cells, Lithium ion batteries, semiconducting
