SUMMARY

The intrinsic carrier density at 440 K for a semiconductor with effective masses of n- and p-carriers of mn* = 0.067me and mp* = 0.48me, and a bandgap of 1.45 eV can be calculated using the formula for intrinsic carrier concentration. The relevant equation is derived from semiconductor physics, specifically relating to temperature and bandgap energy. This discussion emphasizes the importance of understanding effective mass and energy gap in determining carrier density.

Homework Statement



The effective masses of n- and p-carriers in a semiconductor are given by mn* = 0.067me and mp* = 0.48me respectively. The gap width of the semiconductor is 1.45 eV. Use this information to find the intrinsic carrier density at 440 K.

Homework Equations



I have no idea.

The Attempt at a Solution



I obviously had no attempt because I didn't know where to start.
 
Physics news on Phys.org
I suggest looking up the equation. It is very easy to find. Just google "intrinsic carrier density". Good luck.
