Deep-Ultraviolet Photodetection Using Single-Crystalline β-Ga2O3/NiO Heterojunctions
Kuang-Hui Li,Nasir Alfaraj,Chun Hong Kang,Laurentiu Braic,Mohamed N. Hedhili,Zaibing Guo,Tien Khee Ng,Boon S. Ooi +7 more
TL;DR: This work investigates the thin-film growth of a heterostructure stack comprised of n-type β-Ga2O3 and p-type cubic NiO layers grown consecutively on c-plane sapphire using pulsed laser deposition, as well as the fabrication of solar-blind ultraviolet-C photodetectors based on the resulting p-n junction heterodiodes.
Journal ArticleDOI

Chao Zhao,Nasir Alfaraj,Ram Chandra Subedi,Jian-Wei Liang,Abdullah A. Alatawi,Abdullah A. Alhamoud,Mohamed Ebaid,Mohd Sharizal Alias,Tien Khee Ng,Boon S. Ooi +9 more
TL;DR: In this article, a comprehensive review on the recent achievements made in the field of III-nitride nanowires is presented, along with their respective applications, including light-emitting diodes, lasers, photodetectors, and photoelectrodes.
Journal ArticleDOI
Photoinduced entropy of InGaN/GaN p-i-n double-heterostructure nanowires
Nasir Alfaraj,Somak Mitra,Feng Wu,Idris A. Ajia,Bilal Janjua,Aditya Prabaswara,Renad A. Aljefri,Haiding Sun,Tien Khee Ng,Boon S. Ooi,Iman S. Roqan,Xiaohang Li +11 more
TL;DR: In this paper, the photo-induced entropy of InGaN/GaN p-i-n nanowires was investigated using temperature-dependent photoluminescence, and the photocarrier dynamics in the active regions were analyzed.
Journal ArticleDOI
Deep-ultraviolet integrated photonic and optoelectronic devices: A prospect of the hybridization of group III-nitrides, III-oxides, and two-dimensional materials
Nasir Alfaraj,Jung-Wook Min,Chun Hong Kang,Abdullah A. Alatawi,Davide Priante,Ram Chandra Subedi,Malleswararao Tangi,Tien Khee Ng,Boon S. Ooi +8 more
TL;DR: In this paper, the authors provide an overview of aluminum nitride, sapphire, and gallium oxide as platforms for deep-ultraviolet optoelectronic devices, in which they criticize the status of sarspphire as a platform for efficient deep UV devices and detail advancements in device growth and fabrication.
Journal ArticleDOI
Free-space optical channel characterization and experimental validation in a coastal environment.
Wael G. Alheadary,Ki-Hong Park,Nasir Alfaraj,Yujian Guo,Edgars Stegenburgs,Tien Khee Ng,Boon S. Ooi,Mohamed-Slim Alouini +7 more
TL;DR: The proposed models of the channel attenuation coefficient (β) for a coastal environment and related ambient are well validated over the large variation of temperature and humidity over the FSO link in a coastal region and emulated indoor environment.
