摘要：

Instability and temperature oscillations in the melt for idealized Czochralski model for typical parameters of the semiisolating GaAs crystal growth configuration are studied. Critical Gr and Re numbers are determined using linear stability analysis and direct numerical simulation. The impact of the height of the melt on convection structure and critical Gr number are studied. Microgravity alternatives for damping of the temperature oscillations are discussed.
