Journal ArticleDOI
A wide-band UV photodiode based on n-ZnO/p-Si heterojunctions
Naif H. Al-Hardan,Azman Jalar,M.A. Abdul Hamid,Lim Kar Keng,Naser M. Ahmed,Roslinda Shamsudin +5 more
TL;DR: In this article, the fabrication of zinc oxide (ZnO) nanorods on p-type silicon (p-Si) photodiodes was reported, which exhibited an excellent rectifying ratio of 370 at 10-V and 0.29-A/W up to 300-nm.
Journal ArticleDOI
High sensitivity and fast response and recovery times in a ZnO nanorod array/p-Si self-powered ultraviolet detector
TL;DR: In this article, high quality, vertically aligned ZnO nanorods were grown on a silicon substrate, using microwave-assisted chemical bath deposition with polyvinyl alcohol-Zn(OH)2 nanocomposites as seed layer.
Journal ArticleDOI
Fabrication and characterization of V2O5 nanorods based metal–semiconductor–metal photodetector
TL;DR: In this paper, the fabrication and characterization of a metal-semiconductor-metal (MSM) visible photodetector based on V2O5 nanorods is investigated.
Journal ArticleDOI
A highly sensitive flexible SnS thin film photodetector in the ultraviolet to near infrared prepared by chemical bath deposition
Mohamed S. Mahdi,Kamarulazizi Ibrahim,A. Hmood,Naser M. Ahmed,Shrook A. Azzez,Falah I. Mustafa +5 more
TL;DR: In this paper, the photoresponse properties of the fabricated SnS nanostructure in the ultraviolet (UV) to near infrared (NIR) region were studied, and the photodetector was subjected to illumination from four light emitting diodes (LEDs).
Journal ArticleDOI
The effect of post annealing temperature on grain size of indium-tin-oxide for optical and electrical properties improvement
Naser M. Ahmed,Fayroz A. Sabah,H.I. Abdulgafour,Ahmed Alsadig,Ahmed Alsadig,Abdelmoneim Sulieman,M. Alkhoaryef,M. Alkhoaryef +7 more
TL;DR: In this paper, the effect of grain size on the optical and electrical properties of ITO thin films under different annealing temperatures was determined, and it was observed that the grain size was strongly influenced by post-annealing technique and conditions applied, thus providing a tool for enhancing the optical properties of the film.
