  • Abstract
    Frequency responses of Ga1-xAlxAs light-emitting diodes with various Al composition are measured. When the emission peaks become shorter than 7000 Å, the cutoff frequencies decrease abruptly from 15 MHz to 5 MHz. A conclusion is that the frequency response is determined mainly by the lifetime of injected electrons which changes along with the Al composition because of the distribution of electrons between the Γ and X valleys.
