Claim:
1. A method for growing a semiconductor material of type II-VI, comprising: placing a melt of the semiconductor material in a bulb; floating a support element having a through bore on the melt; directly supporting a seed crystal in said bore, by an internal face of said bore, above the melt while maintaining the seed crystal in contact with the melt; sealing the bulb under vacuum or under controlled atmosphere; subjecting the sealed bulb to a temperature gradient for first maintaining the melt in a liquid state and then causing progressive crystallization of the melt from a top surface of the melt towards a bottom of the melt; producing continuous crystallization of the melt from the seed crystal by lowering the temperature gradient; and maintaining the seed crystal in direct contact with the internal face of the bore throughout the continuous crystallization.
