  • Physics of Semiconductor By HC Verma Sir -- Certification Course IITK

    his course will discuss and explain the basic Physics governing Semiconductors. Some experiments demonstrating properties of semiconductors, p-n junctions, transistors and logic gates will be performed to give more intimate feeling of the subject.​ How to Register Start Date: August 15, 2017 Duration: 11-12 weeks Prerequisites: Std 11 passed with Science stream Registration Closes: August 21, 2017 Instructor Incharge Prof. H C Verma Professor, Department of Physics, Indian Institute of Technology, Kanpur The discussion will be roughly at 10+2 and UG (B. Sc. and B. Tech.) first-year level course on semiconductors or electronics. Thus students of std. 12 onwards will benefit most. Teachers who teach this topic are another target group. Basics of Quantum Mechanics Energy levels in pure crystalline solids Conduction mechanism Fermi level and density of states Doping of accepter and donor impurities p-n junctions, mechanism of current under different biasing conditions Special purpose p-n junctions (Zener diodes, photodetectors, solar cell, LED etc.) Theory of transistors Applications like amplification, switching, oscillator etc Binary number system Logic gates. Certificates Certificates will be issued by the Centre for Development of Technical Education (CDTE), Indian Institute of Technology Kanpur. Two kinds of certificates will be issued to the qualifying students based on their involvement and performance. Competency Certificate This will be given to the participants who would have viewed at least 90% of the lectures and scored a minimum percentage in the quizzes which will be decided by the course instructor after the examinations. Participation Certificate This will be given to the participants who would have viewed at least 90% of the lectures. A lecture will be treated as “viewed” only if it is viewed from the beginning to the end. One can see the video in multiple sittings as the management system keeps the record of that. Please note that you will have to view the videos from the course website itself. Viewing downloaded videos or viewing them from YouTube or from others' account will not be counted for certificates.
