Highly sensitive and selective gas sensors using p-type oxide semiconductors: Overview

Hyo Joong Kim, +1 more
- 01 Mar 2014 - 
TL;DR: In this article, high performance gas sensors prepared using p-type oxide semiconductors such as NiO, CuO, Cr2O3, Co3O4, and Mn3O3 were reviewed.
Journal ArticleDOI

Gas sensors using hierarchical and hollow oxide nanostructures: Overview

Jong Heun Lee
- 18 Jun 2009 - 
TL;DR: In this article, the authors show that hierarchical and hollow oxide nanostructures increase both the gas response and response speed simultaneously and substantially, which can be explained by the rapid and effective gas diffusion toward the entire sensing surfaces via the porous structures.
Journal ArticleDOI

Gas sensing properties of defect-controlled ZnO-nanowire gas sensor

M. W. Ahn, +7 more
- 29 Dec 2008 - 
TL;DR: In this article, the effect of oxygen-vacancy-related defects on gas-sensing properties of ZnO-nanowire gas sensors was investigated and it was shown that the sensitivity of the sensors to NO2 gas is linearly proportional to the photoluminescence intensity.
Journal ArticleDOI

Novel fabrication of an SnO2 nanowire gas sensor with high sensitivity

Youngjin Choi, +5 more
- 05 Mar 2008 - 
TL;DR: A nanowire-based gas sensor is fabricated using a simple method of growing SnO(2) nanowires bridging the gap between two pre-patterned Au catalysts, in which the electrical contacts to the Nanowires are self-assembled during the synthesis of the nanOWires.
Journal ArticleDOI

Thin-Wall Assembled SnO2 Fibers Functionalized by Catalytic Pt Nanoparticles and their Superior Exhaled-Breath-Sensing Properties for the Diagnosis of Diabetes

Jungwoo Shin, +7 more
- 20 May 2013 - 
TL;DR: In this paper, the authors demonstrate the feasibility of thin-wall assembled metal oxide-based breath sensors for the accurate diagnosis of diabetes and potential detection of lung cancer, which are markers used for the diagnosis of Diabetes and lung cancer.
