Solid State Physics

By Prof. Nirmal Ganguli   |   IISER Bhopal
Learners enrolled: 793
This course is designed to introduce the structure, electronic, and other fundamental properties of solids to the students. It is supposed to be the fundamental course on solid state physics, covering in details the representation of crystal structure, symmetries in solid, x-ray diffraction, bonding, transport properties, electronic structure, vibration of the lattice, outline of magnetism, and superconductivity. We will carefully develop the concepts in logical steps and solve problems, resulting in a concrete understanding of the topics. While a course covering these topics is mandatory in almost every university around the world for the Physics students, Chemistry and Electrical Engineering students interested in research of condensed matter physics may benefit from the course.

INTENDED AUDIENCE    :   BSc third year, MSc first year    
PREREQUISITES             :   One should have some idea of quantum mechanics, statistical mechanics, vector algebra & calculus, and simple geometry.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 23 October 2021 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IISER Bhopal .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
