effective mass of electron

[@sujathak8101]

Dear your explanation is excellent But the mass of the particle is not zero (m#0)when k=0

[@prasantachowdhury2606]

at inflection point effective mass is infinity and velocity is constant. but a particle with infinite mass should be rest....so why it has a constant velocity?

Full explanation of E-k diagram.. dependence of energy, velocity and mass on wave vector k .. i could found only here... Thanks!

[@memoriislife9046]

Extra brilliant never miss it...gud job sir

[@sharifhasan4720]

you should get a big thank you....

[@ranjnagupta8754]

Very good sir

A silicon pm junction at T = 300 K has doping concentrations of Ng = 3 x 10 cm- and N = 8 x 10s cm-, and has a cross-sectional area of A = 5 x 10-$ cm'. Deter- mine thejunction capacitance at (a) VR = 2 v and (b) Vr = 5 V

Very nice

How the external force is influenced???

[@hercolus-2003]

h bar is h/2pi in 1:45 not 2pi/h

[@suddalapadmaja6089]

Excellent sir

[@gudiachoudhary1278]

Outstanding sir

[@harisanth7568]

Wonderful explanation sir

[@abhinavcheruku5027]

Am I the only one who can't see sir but hear him??

[@MAKhan-xy5vz]

excellent

[@mkhforkids3571]

What is influence point.....and what is k

[@mohsinshah6857]

Inflection point?

[@RaushanKumar-gt9ly]

K is wave vector

Thank u sir. For clearing my concepts 👍
