Journal ArticleDOI
Selective-area epitaxy of pure wurtzite InP nanowires: high quantum efficiency and room-temperature lasing.
Qian Gao,Dhruv Saxena,Fan Wang,Lan Fu,Sudha Mokkapati,Yanan Guo,Li Li,Jennifer Wong-Leung,Philippe Caroff,Hark Hoe Tan,Chennupati Jagadish +10 more
TL;DR: Growth of stacking-fault-free and taper-free wurtzite InP nanowires with diameters ranging from 80 to 600 nm using selective-area metal-organic vapor-phase epitaxy and experimentally determine a quantum efficiency of ∼50%, which is on par with InP epilayers are reported.
Journal ArticleDOI
Mode Profiling of Semiconductor Nanowire Lasers.
TL;DR: The experimentally obtained polarization dependent far-field profiles match very well with numerical simulations and enable unambiguous identification of the lasing mode(s).
Journal ArticleDOI
Efficiency enhancement of axial junction InP single nanowire solar cells by dielectric coating
Zhiqin Zhong,Zhiqin Zhong,Ziyuan Li,Qian Gao,Zhe Li,Kun Peng,Li Li,Sudha Mokkapati,Kaushal Vora,Jiang Wu,Jiang Wu,Guojun Zhang,Zhiming Wang,Lan Fu,Hark Hoe Tan,Chennupati Jagadish +15 more
TL;DR: In this paper, a single axial p-i-n junction InP nanowire (NW) solar cells were constructed by selective-area metal organic vapor phase epitaxy (SA-MOVPE) technique.
Journal ArticleDOI
Engineering Highly Interconnected Neuronal Networks on Nanowire Scaffolds
Vini Gautam,Shagufta Naureen,Naeem Shahid,Qian Gao,Yi Wang,David R. Nisbet,Chennupati Jagadish,Vincent Ricardo Daria +7 more
TL;DR: It is shown, for the first time, that an isotropic arrangement of indium phosphide (InP) nanowires can serve as physical cues for guiding neurite growth and aid in forming a network with neighboring neurons.
Journal ArticleDOI
Simultaneous Selective-Area and Vapor–Liquid–Solid Growth of InP Nanowire Arrays
Qian Gao,Vladimir G. Dubrovskii,Vladimir G. Dubrovskii,Vladimir G. Dubrovskii,Philippe Caroff,Jennifer Wong-Leung,Li Li,Yanan Guo,Lan Fu,Hark Hoe Tan,Chennupati Jagadish +10 more
TL;DR: A detailed growth study revealing that fundamental growth mechanisms of pure wurtzite InP ⟨111⟩A nanowires can indeed differ significantly from the simple picture of a facet-limited selective-area growth process.
