Numerical Simulation of CdTe Growth with Vertical Bridgman Method
|
Abstract:
A Galerkin finite element method is employed to calculate the thermal fields,melt flow and shape of the crystal melt interface.The influence of the growth parameters on the crystal melt interface is analyzed in detail.The simulations show that at a lower growth rate,a flatter interface would be obtained.Increasing the temperature gradients has also proved effective to improve the interface.Heat flow analysis shows that the heat exchange mainly concentrates near the gradient zone during the middle stage of the growth
