V_b is defined as V_n +V_p(adsbygoogle = window.adsbygoogle || []).push({});

v_n = (E_f-E_i)/kt

i dont know what is the accurate meening of V_b

i know that it takes values around 0.7v

and i know that 0.7 volts is the voltage that makes the diode to become a conductor

so what is V_b

?

i was also told

that if E_g gets smaller then n_i gets larger then V_b gets smaller

i cant understand why??

i know that E_g is the differnce between valce band and condactivity band

n_i is the density of negative charges =and positive charges in non doped material

how the change of one affect the other in the appointed way?
