Persistent photoconductivity zno
Web19. júl 2012 · The persistent photoconductivity is suppressed through oxygen plasma treatment of the channel surface which significantly reduces the density of oxygen vacancy confirmed by XPS measurements. The proper gate bias-control further reduces recovery time. The UV-TFT configuration is particularly suitable for making large-area imaging arrays. Web4.2 Relation to PPC Persistent photoconductivity has been predicted theoretically to arise from photoexcited oxygen vacancies, creating shallow donor states.17 Although oxygen …
