N2 - In this paper, we give a brief account of pair-tunneling in GaAs quantum dots. We show that while GaAs is a weakly-polar semiconductor, coupling to optical phonons is sufficiently strong to mediate a negative-U pairing state. As a result, two electrons can tunnel coherently from the source lead to the quantum dot as a Cooper pair would across a Josephson junction. PACS numbers:73.20.Dx,71.38.+i,72.20.My,72.10.-d.
