In a particular semiconductor, the fermi energy is located 0.4 ev above the intrinsic

energy with ef – ei = 0.4 ev. assume that the silicon semiconductor is at room

temperature and the intrinsic carrier concentration, ni = 1010 cm-3

. (boltzmann constant,

k = 8.617 x 10-5 ev/k.)

a. determine the conduction electron concentration.

b. determine hole concentration.

c. calculate the product of n * p.

in a particular semiconductor, the fermi energy is located 0.3 ev below the intrinsic

energy with ei – ef = 0.3 ev. assume that the silicon semiconductor is at room

temperature and the intrinsic carrier concentration, ni = 1010 cm-3

. (boltzmann constant,

k = 8.617 x 10-5 ev/k.)

a. determine the conduction electron concentration.

b. determine hole concentration.

c. calculate the product of n * p. compare to your answer in problem 8(c). is this

a coincidence? (hint: multiply the equations for n and p.)

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
