TL;DR: A new fabrication method of a UV photosensor based on ZnO nanowires using dielectrophoresis using DEP technology could detect UV light down to 10 nW cm(-2) intensity, indicating a higher UV sensitivity.
Journal ArticleDOI
Growth mechanism of ZnO nanorods from nanoparticles formed in a laser ablation plume
TL;DR: In this paper, the authors synthesize ZnO nanorods by pulsed-laser ablation at comparatively high gas pressures without using a catalyst, and they found that nanoparticles formed by condensation of ablated particles in the laser ablation plume play an important role in nanorod growth.
Journal ArticleDOI
Comparative study on emission characteristics of extreme ultraviolet radiation from CO2 and Nd:YAG laser-produced tin plasmas
TL;DR: In this paper, a comparison of the emission characteristics of an extreme ultraviolet (EUV) light between the CO2 and the Nd:YAG laser-produced plasmas (LPP) with a solid tin target is reported.
Journal ArticleDOI
Nano-Sized Hollow Bump Array Generated by Single Femtosecond Laser Pulse
TL;DR: In this paper, the generation of a nano-sized hollow bump array of gold thin film by uniformly spaced melting and inflation of the film induced by a single shot of four interfering laser beams is reported.
Journal ArticleDOI
Synthesis of ZnO nanorods by nanoparticle assisted pulsed-laser deposition
TL;DR: In this paper, nanorods with a size of approximately 300 nm in average diameter and 6 µm in length were grown on sapphire substrates heated at approximately 700°C by the pulsed-laser deposition technique without any catalyst.
