The barrier has a valence band energy substantially equal to the valence band energy of the photo absorber, and a thickness and a conductance band gap sufficient to allow tunneling of minority carriers, and block the flow of thermalized majority carriers from the photo absorber to the contact area. A P-doped or N-doped semiconductor may be utilized. The photoabsorber layer may extend past the one or more individual sections of the contact areas in the direction across the photo-detector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reduced dark current photodetector","description":"A photodetector comprising a doped semiconductor photoabsorber, a barrier layer in contact with the photo absorber layer on one side, and at least one doped semiconductor contact area on the opposite ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11961936","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.
