An abrupt si p-n junction has the following parameters: (15 pts) n-side: nd 5 x 1018 cm-3 p-side: na1017 cm-3 junction areaa 102cm2 carrier lifetimes 2us a) find the built-in potential vo. b) find the reverse saturation current io c) find the total minority carrier charge on each side of the diode at a forward current of 1 ma

hey , the answer is c

true tan speed = ang vel x radius

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
