Purushothaman Varadhan,Hui-Chun Fu,Davide Priante,José Ramón Durán Retamal,Chao Zhao,Mohamed Ebaid,Tien Khee Ng,Idris A. Ajia,Somak Mitra,Iman S. Roqan,Boon S. Ooi,Jr-Hau He +11 more
TL;DR: This work addresses the issue of surface states in GaN nanowire photoelectrodes by employing a simple and low-cost surface treatment method, which utilizes an organic thiol compound (i.e., 1,2-ethanedithiol).
Journal ArticleDOI
Probing surface band bending of surface-engineered metal oxide nanowires.
Cheng-Ying Chen,Cheng-Ying Chen,José Ramón Durán Retamal,I-Wen Wu,Der Hsien Lien,Mingwei Chen,Yong Ding,Yu-Lun Chueh,Chih-I Wu,Jr-Hau He +9 more
TL;DR: In this article, the surface band bending (SBB) was probed by ultraviolet photoelectron spectroscopy (UPS) in conjunction with field effect transistor measurements on the incompletely depleted ZnO nanowires.
Journal ArticleDOI
Going beyond 4 Gbps data rate by employing RGB laser diodes for visible light communication
Bilal Janjua,Hassan M. Oubei,José Ramón Durán Retamal,Tien Khee Ng,Cheng-Ting Tsai,Huai-Yung Wang,Yu-Chieh Chi,Hao-Chung Kuo,Gong-Ru Lin,Jr-Hau He,Boon S. Ooi +10 more
TL;DR: This work highlighted that a tradeoff exists in operating the blue LDs at optimum bias condition while maintaining good color temperature, and achieved significantly higher data rates by using LDs and spectral-efficient orthogonal frequency division multiplexing encoding scheme.
Journal ArticleDOI
Schottky junctions on perovskite single crystals: light-modulated dielectric constant and self-biased photodetection
P.A. Shaikh,Dong Shi,José Ramón Durán Retamal,Arif D. Sheikh,Mohammed Haque,Chen-Fang Kang,Jr-Hau He,Osman M. Bakr,Tao Wu +8 more
TL;DR: In this paper, the physical properties of Schottky-junctions formed on hybrid perovskite CH3NH3PbBr3 single crystals were investigated and a photodetectivity of 1.4 × 1010 Jones was obtained at zero bias, which increases to 7.1 × 1011 Jones at a bias of +3 V.
Journal ArticleDOI
Van der Waals heteroepitaxial AZO/NiO/AZO/muscovite (ANA/muscovite) transparent flexible memristor
Van Qui Le,Thi Hien Do,José Ramón Durán Retamal,Pao Wen Shao,Yu Hong Lai,Wen-Wei Wu,Jr-Hau He,Yu-Lun Chueh,Yu-Lun Chueh,Ying-Hao Chu +9 more
TL;DR: In this article, the van der Waals heteroepitaxial AZO/NiO/AZO/muscovite (ANA/musmovite) memristor was designed for a transparent soft device with high performance with a ON/OFF resistance ratio > 105, stable endurance to 103 cycles and long retention time of 105 s.
