    Junction Capacitance in a GaAs Photodiode

    Confirmation that the equations I've given are correct and then values for ε0 = permittivity of free space εGgAs = GaAs dielectric constant μ = Mobility of electrons ρ = resitivity Vbi = built-in voltage

    Junction Capacitance in a GaAs Photodiode

    It's custom part. My colleague did a calculation a while back and came up 250pF at 0V I'm getting femtoFarads which is definitely not right!

    Junction Capacitance in a GaAs Photodiode

    I am trying to get an estimation the junction capacitance of my GaAs Photodiode with respect to varying bias voltages. My Semiconductor Physics online textbook gives the following equations with ε0 = permittivity of free space εGgAs = GaAs dielectric constant μ = Mobility of...
