What limits the cascade process of free carrier capture to very low sample temperatures?

Some shallow-impurity atoms capture free carriers by emitting acoustical phonons. This process requires a ladder of closely-spaced energy levels connecting an energy-level associated with this...

Can a shallow acceptor capture conduction electrons by multiphonon emission with optical phonons in semiconductors?

I am working with a deep level impurities can capture free carriers by multiphonon emission of optical phonons or by emitting a photon. I don't see why a shallow acceptor can't do the same thing....
