Gallium melt satd. with gallium arsenide - for use as source for gas-phase epitaxy
Prepn. of Ga melt satd. with GaAs by passing over molten Ga a mixt. of AsCl3 and H2 is improved by reducing the AsCl3 feed rate as soon as a GaAs crust, which is formed on the Ga melt, reaches such a thickness that the diffusion of As into the inner of the Ga melt is hindered; the feeding of AsCl3 i...

| description | Prepn. of Ga melt satd. with GaAs by passing over molten Ga a mixt. of AsCl3 and H2 is improved by reducing the AsCl3 feed rate as soon as a GaAs crust, which is formed on the Ga melt, reaches such a thickness that the diffusion of As into the inner of the Ga melt is hindered; the feeding of AsCl3 is resumed when the GaAs crust partly dissolves in the melt so that As can again diffuse into Ga. This cycle is repeated until saturation of the melt with GaAs is reached. By this method, excessive development of the GaAs crust (which is undesirable for the gas phase epitaxy) is prevented, and saturation of Ga melt with As is accelerated. |
