ABSTRACT
Nanosecond resolution time-resolved x-ray diffraction has been used to make the first measurements of the liquid-solid interface overheating and undercooling in germanium. The results show an orientation-dependent undercooling for growth on (111) and (001) faces. For both the (111) and (001) faces the velocity versus temperature interface response function has a slope of ∼5 K/(m/s), except for undercooling on the (111) face where the slope is 20 K/(m/s).
