A gas driven apparatus and method that can be useful for growing crystalline materials are provided. The gas driven rotation apparatus can include one or more rotatable substrate support members, each of which can be configured to support at least one substrate having a growth surface oriented in a downwardly facing position. The gas driven rotation apparatus can further include one or more drive gas channels adapted to direct the flow of a drive gas to rotate the substrate support member. One or more substrates can be positioned in the apparatus so that the growth surface of each substrate is downwardly oriented. A drive gas can flow through the drive gas channel to rotate the substrate. During rotation, reactant gases can be introduced to contact the downwardly facing growth surface, and epitaxial layers of a crystalline material can thereby be grown in a downward direction. |
