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.
