Multi-layered structures containing GaN on SOD (silicon/diamond/silicon) substrates are described. The unique substrate/epilayer combination can provide electronic materials suitable for high-power and opto-electronic devices without commonly observed limitations due to excess heat during device operation. The resulting devices have built-in thermal heat spreading capability that result in better performance and higher reliability.
