How does the injected density change if the temperature is 77 K?

Consider the semiconductor alloy In GaAsP with a band gap of 0.8 eV. The electron and hole masses are 0.04 m0, and 0.35 m0, respectively. Calculate the injected electron and hole densities needed at 300 K to cause inversion for the electrons and holes at the band edge energies. How does the injected density change if the temperature is 77 K? Use the Joyce-Dixon approximation.
