Abstract
Instability and temperature oscillations in the melt for idealized Czochral ski model for typical parameters of the semiisolating GaAs crystal growth c onfiguration are studied. Critical Gr and Re numbers are determined using l inear stability analysis and direct numerical simulation. The impact of the height of the melt on convection structure and critical Gr number are stud ied. Microgravity alternatives for damping of the temperature oscillations are discussed.
