Rapid Crystallization of Amorophous Gallium Produced by Laser Quenching

Abstract

ABSTRACTTransient conductance measurements reveal the metastability of amorphous Gallium (a-Ga): Gallium can be amorphized for a certain “lifetime” at temperatures as high as 60 K, i.e. well above the crystallization temperature of 16 K.For the first time the lower part of the C-shaped transition curve in a TTT-diagram can be measured for a pure metal. The results are in good agreement with undercooling behavior of liquid Ga-droplets.
