Comment on " Critical Currents in Ballistic Two-dimensional Inas-based Superconducting Weak Links " Typeset Using Revt E X

In ballistic Josephson junctions the experimentally observed iv-characteristics deviate from the theoretically predicted behaviour. Recently, Heida et al. Phys. Rev. B 60, 13135 (1999) discussed this problem and offered an explanation for the discrepancy. Considering this explanation, several contradictions to the authors' data as well as to other… (More)
