At 46:38 he mentioned about finding blue light ... and in 2014 Nobel Prize in physics is given to that very discovery... Sadoway is the greatest Chemistry teacher .....

I have never seen such teaching skills before... Amazing

[@sahilsagwekar]

watch physics from walter lewin they are the best physics lectures

[@ekaterinafilatova8883]

Thank you Prof. Donald Sadoway. It is the best chemistry lectures that I have ever attended! Thank you MIT!

[@johniedesk1]

Great stuff, great explanation of semi conductors

[@datle7225]

Thank you Prof. Donald Sadoway. Great lectures.

[@RandaZarrouk137]

MIT you are the best !!

[@Leowlion11]

Makes me grin and chuckle to see the rating of lec 13 and then lec 14 - nailed it!

Phos intro at 29:40 approx., 42:05 great point re electron distance from donor vs Si-Si bond distance

[@Khalfallah]

Great course and teacher thanks MIT

[@samk8890]

great teacher good explaination thank you mit

[@michaelgonzalez9058]

U do that with one at a time

bestttttttttttttt lecture so far

[@hikguru]

The area on the n(E)/E vs. E curve for E> 1.1 is 1e-19 at room temperature. If there are ~1e23 Si atoms/cc then you have 4 e 23 valence electrons/cc, which means the number of electrons with enough thermal energy to go to CB = 1.1e-19*4e23 which is

When he said the surface is flat to one - atom; is this true of any material that has a uniform surface (i.e. everything is absolutely on the same plane?)... and I guess crystalline structure

this guy is the Harvey specter of chemistry

[@viveksubedi4877]

Wow prof

[@blusparx500]

Even MIT students average a 66 on a celebration. Guess that’s typical of any college (n of 2)
