Abstract

Using a thermocouple immersed into the melt, temperature fluctuation in molten GaAs was directly measured over a temperature ranging from 160 K above to 28 K below the melting point; temperature fluctuation in the melt was observed even for supercooled melts. Melt viscosity was estimated from the temperature fluctuation. Melt viscosity increased nonlogarithmically vs. temperature under the supercooled condition. It could be inferred that a short range ordering, such as second and/or third nearest neighbor atoms ordering, was formed around the melting point.
