Use the data in Table 13.5 to estimate a band gap for the semiconductor GaP. Use this
Question:
Use the data in Table 13.5 to estimate a band gap for the semiconductor GaP. Use this to calculate the wavelength of light that is emitted when an electron drops from the conduction band to the valence band. Is this consistent with the observed green light of gallium phosphide LEDs?
Table 13.5.
