The chamber may define an internal space and include a light emission window. The at least one semiconductor light emitting device may be on the light emission window and include a first conductivity type nitride semiconductor layer, an undoped nitride semiconductor layer, and an active layer between the first conductivity type nitride semiconductor layer and the undoped nitride semiconductor layer. The electron beam irradiation source may be in the internal space of the chamber and configured to irradiate an electron beam onto the undoped nitride semiconductor layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultraviolet light emitting apparatus","description":"An ultraviolet light emitting apparatus may include a chamber, at least one semiconductor light emitting device, an electron beam irradiation source, and first and second connection electrodes configu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9640717","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.
