AbstractIn this SBIR program, Structured Materials Industries, Inc. www.structuredmaterials.com (SMI) will develop infrared-transparent, electromagnetic shielding coatings that can be applied to electro-optic sensor windows and domes. The coatings will be based on films of indium nitride (InN), deposited by metal organic chemical vapor deposition (MOCVD). InN is a refractory material with known infrared transparency. InN can be readily alloy with gallium nitride (GaN) and/or aluminum nitride (AlN) to create a family of electrically conductive, infrared transparent coating materials. InN and these related group III nitride materials have already been extensively developed for electro-optic applications. The proposed MOCVD technology can deposit high quality group III nitride coatings, with very low stress and excellent uniformity on 3-dimensional substrates.
