VARIABLE-TEMPERATURE VAPOR DEPOSITION PROCESS
A method of growing a single crystal diamond material synthesized using a homoepitaxial chemical vapor deposition process. The method includes the steps of placing a free-standing diamond starting seed substrate on a substrate holder within a reaction chamber for chemical vapor deposition; feeding a process gas into the reaction chamber, the process gas including hydrogen gas; igniting a plasma within the reaction chamber to activate the process gas by adjusting the substrate temperature to increase to a first target substrate temperature; adding a carbon-containing gas to the process gas once the substrate temperature is at or near the first target substrate temperature to initiate diamond growth; and adjusting the substrate temperature to a second target substrate temperature that is different from the first target substrate temperature during the diamond growth.
