Abstract
Au/In-bilayers with a thickness ratio corresponding to AuIn2 have been bombarded at different temperatures T(S) < 15, 77, 125 and 180 K with 350 keV Kr+-ions. The resulting ion beam mixing (IM) is monitored by in situ resistance measurements. At T(S) less-than-or-equal-to 125 K, IM leads to the formation of an amorphous phase, while at T(S) = 180 K the disordered crystalline AuIn2-phase is obtained. The mixing effici encies extracted from the sputter-corrected resistance data are found to be temperature-independent for T(S) less-than-or-equal-to 180 K and are consistent with the predictions of the thermal spike model.
