Each opening exposes a surface of the silicon substrate having a (111) crystalline plane. A buffer layer is then formed on the exposed surfaces of the patterned dielectric material structures and the silicon substrate. A dual phase Group III nitride structure including a cubic phase region is formed filling a space between each neighboring pair of the patterned dielectric material structures and one of the openings located beneath the space. Finally, at least one Group III nitride layer is epitaxially deposited over the cubic phase region of the dual phase Group III nitride structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polarization free gallium nitride-based photonic devices on nanopatterned silicon","description":"After forming patterned dielectric material structures over a (100) silicon substrate, portions of the silicon substrate that are not covered by the patterned dielectric material structures are remove","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608160","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
