Answer:
Explanation:
We can write the expression here, but the point of the problem seems to be to see if you can manipulate the controls on the answer box to reproduce that expression.

Answer:
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.
Explanation:
Solution:
At 300K:
Let suppose mobility of electron in intrinsic semiconductor =
Mobility of electron in intrinsic semiconductor is:
= 1300
/volt.sec
Let suppose mobility of hole in intrinsic semiconductor =
= 500
/volt.sec
We know that, intrinsic silicon semiconductor has equal number of holes and electrons. So,
At 300 K
Intrinsic Carrier Concentration = 1.5 x /
= C
And,
Conductivity of intrinsic Silicon is:
σ = C x ( +
) e
e = 1.6 x C
So, plugging in the values, we get:
σ = C x ( +
) e
σ = 1.5 x x (500 + 1300) x 1.6 x
σ = 4.32 x
So, now we can find the resistivity.
Resistivity = 1/σ
Resistivity = 1/ 4.32 x
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.
