Good lord... Did he just managed to explain clearly the wave/particle duality of quantum mechanic in a way that a 12 years old can understand? I'm amazed at each video. This guy deserves a monument, and to be canonized as St Teacher (and I'm not religious)
only nptel is the one stop solutions to prepare for ESE with relevant concepts....i understood this after spending years in coaching classes..Thank u very much sir for these awesome lectures.
good to join if u dnt hv basics of ur subjects,bt if u know some subjects then jst take notes of any good coaching and make ur own notes along with nptel,and in those subjects in which u r weak join coaching only for those as subject-wise classes if u want good answers fr these questions better to join a Facebook page that is LEARN GATE FREE...that also helps me a lot fr my queries ..
Dear Sir, thanks a lot for making this lectures public, this is of much help for me. I kindly ask if the mentioned CD of exercise and solved problems is avalable for download. Would appreciate to have it, Thank you.
Sir you are an amazing teacher.I have a question there is a law that charge cannot be there without mass but mass can be there without charge then how is a hole possible without mass?
@0112ec071083 The electron is frees, not the atom ;-). It's free when the photon has enough energy to break the bond. In total the photon and electron in the bond have to have 1,12eV for Silizium.

hey iam going to attend coaching classes,not yet paid ,were they good?
please suggest the best coaching .

Even for GATE I prefer Nptel lectures
RLC for gate is good
I can't believe I just understood and got an intuitive grasp of the wave/particle duality...
This guy is a super-hero, with alien teaching powers
these lectures are pure diamond over the internet
An extra-ordinary lecture. Elegance at it's peak.
best man to teach semiconductor devices.salute u sir.
MUCH CLEARER ........CONCEPTS TAUGHT BY KARMALKAR SIR.....THANKU SIR....
Thank you sir! students are fortunate to get teachers like you :)
Really good lecture! Prof. Karmalkar gives a wonderful insight into the core concepts of solid state devices. Thanks for the post!
This one is heck of a Genius teacher! we feel Proud of having a teacher like you.
It is a great contribution.Thank you all.It realy helped me in my study.
KEEEEEP IT PLEASE!
Dr. Karmalkar is an intellectual stud.
Very good explanation so far, but l'm still unsure how he'll explain the complicated quantum physics involved in this subject mathematically!
What a teaching i big thanks to IIT, now all my doubts are cleared..
Unbeleivably simple and clear!!
Prof. Karmalkar, thank you very much!!
realy very deep conceptual lacture and all daut clear when looking the nptl lacture thanku sir

our IIT R teachers are also good.. but You are really best.....

thank you very much!
Thank you very much sir.
Highly useful
thanks sir very clear and depth
Sir is this right that holes are positively charged or we can only assume it
Holes are positive charged ....It's not assumption it's fact..
Thanks!

Downvoters are from iit bombay
thank u very much for the valuable lectures
