Abstract
This Small Business Innovation Research Phase I project will investigate the feasibility of growth of high-quality and low-cost bulk aluminum nitride (AlN) substrates by vapor phase deposition. The performance of nitride-based devices, such as light-emitting diodes (LEDs), lasers, and transistors, is limited by epitaxial growth on foreign substrates. LEDs with aluminum gallium nitride (AlGaN) active regions emitting in the ultraviolet (UV) spectrum are limited to an efficiency of ~1%, but are especially suited to growth on AlN due to the lattice match. Thus, there is an opportunity to enhance the performance of these devices by using closely-matched AlN substrates with low defect density. The proposed approach to grow bulk AlN utilizes a novel vapor phase deposition method which uses low cost consumables, is scalable to high product rates, and is capable of high quality. The research objectives are to demonstrate AlN crystals of excellent crystal quality with low dislocation density (10000/square cm), grown at a high growth rate of 1 mm/hr. The successful completion of these objectives will lay the groundwork for high-volume and low-cost production of high quality AlN substrates. The broader impact/commercial potential of this project will be a result of a dramatic increase in the availability of low-cost AlN substrates for use in optoelectronics and energy conversion devices. The development of commercially viable AlN substrates will enable revolutionary performance enhancements for many devices, specifically including UV LEDs, in terms of output power, energy efficiency, and lifetime. High efficiency UV LEDs will have a broad range of applications including replacement of toxic mercury vapor lamps used for UV purification, UV curing, and chemical sensors, and UV LEDs will enable new applications which require compact and robust UV emitters. One of the most important benefits to society is the ability to provide an effective, low cost, and chemical free method to disinfect water for human consumption. Finally, as a supplier of a high-value enabling semiconductor material, we intend to market to smaller niche semiconductor manufacturing companies in the U.S. as early adopters of AlN substrates, thus strengthening the U.S. semiconductor manufacturing industry.
