A single crystal intrinsic semiconductor is at a temperature of $300$ $\text{K}$ with effective density of states for holes twice that of electrons. The thermal voltage is $26$ mV. The intrinsic Fermi level is shifted from mid-bandgap energy level by
- $18.02 \: meV$
- $9.01 \: meV$
- $13.45 \: meV$
- $26.90 \: meV$
