Homework Statement
Consider a circuit that consists on a resistor of an intrinsic semiconductor R and a capacitor C in series. The voltage between the terminals of the circuit is U, which is an alternated sinusoidal voltage.
U1, which is the voltage in the capacitor as a phase difference of 30 degrees from the voltage U for a temperature of 300K and a phase difference of 9 degrees at 330 K
What is the energy gap in the
Homework Equations
I = jwC Uc
The Attempt at a Solution
I have no idea where to start.
I know that I have to relate my voltages but I have no idea how, since they just say they have a ohase difference.
I know that the fraction between the phasors of U and U1 must then be $$e^{j\pi/6}$$. But how do I relate this to the resistance?
This j however confuses me...
Then after I get my resistances I know how to proceed
By applying:
$$R/R'=e^{\frac{W_G(T'-T)}{2KTT'}}$$
And solving this equation I get W_G.
So yeah basically my problem is how to work the circuit to find the resistance.
Can someone give me a little help?
