where can i find video lectures on electrical properties of metals and semiconductors..(for second semester electrical engineering students)

Question

shivaniits · Answer

you can search nptel ,mit lectures and indeed feymann lectures would also help you..!!

anonymous · Answer

i could'nt find all the concepts in one location in mit they were scattered and also most of them seemed too advance..i searched nptel where it was better..but i still need to look for something better...and this is my syllabus....please suggest me some good sites..


UNIT I ELECTRICAL PROPERTIES OF METALS 9
Classical theory: Drude model - thermal conductivity, thermal resistance - electrical conductivity
of nonmetals: semiconductors, ionic crystals and glasses - thin metal films: conductivity and
resistivity - Schrödinger wave equation - particle in a box - Tunneling (qualitative) degenerate
states - Fermi-Dirac statistics - density of states: electron concentration and Fermi level - band
theory of solids: energy band formation (qualitative) - electron effective mass.
UNIT II SEMICONDUCTORS 9
Intrinsic semiconductors: energy band-diagram - direct and indirect band gap semiconductors
- carrier concentrations and conductivity - extrinsic semiconductors: compensation doping -
temperature dependence of conductivity - degenerate and nondegenerate semiconductors
- recombination and minority carrier injection: direct and indirect recombination - minority
carrier lifetime - diffusion and conduction equations and random motion - optical absorption -
Hall effect and devices - Ohmic contacts - Schottky diode and solar cell.

http://nptel.iitm.ac.in/courses.php?disciplineId=122 these are semester 1 and 2 suggested reading according to the nptel ..why don't you look at them..?? i think they will cover all your crude concepts..!!

shivaniits · Answer

they contain video and web lectures too that may serve as good material as notes..
