    • Levine uses the term “optical gain” to describe the gain for photogenerated carriers (Ref. 1). However, since the gain in this letter applies to thermally generated as well as optically generated carriers, the more common term “photoconductive gain” is used.

    • This noise source is sometimes called shot noise (Ref. 1), which is closely related to GR noise.

    • Some fraction of carriers are also reflected from the well. The mean effect of carrier reflection is implicitly included in the value of [formula omitted] for a given applied electric field. Furthermore, since reflection alters the velocity of mobile carriers, but does not affect their number, statistical fluctuations in the reflection rate appear as Johnson noise, but do not contribute to GR noise.

    • As shown below, the ejection rate is also the appropriate generation rate to balance the capture rate in steady state.
