Aerosol assisted chemical vapour deposition of nanostructured ZnO thin films for NO2 and ethanol monitoring
Gas response control through structural and defect engineering in metal oxides are critical approaches to realize high performance sensors. Herein, we present the fabrication of ZnO thin films containing nanosized structures and high concentration of zinc interstitials for NO2 and ethanol monitoring. The target materials were fabricated by aerosol ...
First principles investigations of the structural, electrical and optical properties of iron-doped zinc oxide (0001) sur...
A first principles density function investigation of the structural, electrical and optical properties of iron-doped ZnO (0 0 0 1) surfaces is conducted by considering the substitutional sites in the three relaxed ZnsbndO bilayers and the interstitial site in the centre of the octahedron surrounded by zinc atoms. Calculations are performed with the...
Hierarchically nanostructured vanadium nitride microspheres assembled with porous nanosheets fabricated by a template-fr...
In this research, hierarchically nanostructured vanadium nitride (VN) microspheres were successfully prepared by a template-free method. ZnO, behaving as a sacrificial phase, was selectively leached out during nitridation of Zn-3(OH)(2)(V2O7)center dot(H2O)(2) microspheres with NH3, inducing a network structure. The VN microsphere was assembled wit...
The mechanism of growth of ZnO nanorods by reactive sputtering
DC reactive magnetron sputtering of zinc target in argon-oxygen sputtering atmosphere has been used to grow ZnO thin films/nanorods on Si in a wide substrate temperature range of 300-750 degrees C and under different sputtering conditions, namely, DC power, sputtering pressure and oxygen percentage in the sputtering atmosphere. Powder X-ray diffrac...
Ag-Modified In2O3 Nanoparticles for Highly Sensitive and Selective Ethanol Alarming
...
Pure In2O3 nanoparticles are prepared by a facile precipitation method and are further modified by Ag. The synthesized samples are characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, Raman and UV-Vis spectra. The results show the successful heterojunction formatio...
Amplifying the Signal of Metal Oxide Gas Sensors for Low Concentration Gas Detection
Nowadays, detection of trace concentration gases is still challenging for portable sensors, especially for the low-cost and easily operated metal-oxide-semiconductor (MOX) gas sensors. In this paper, a widely applicable amplification circuit is designed and fabricated to evidently enhance the signal of the MOX sensors by adding a field effect trans...
Zinc oxide growth and its interfaces with metals observed by photoemission
Thin films are a common way to add functionality to flat glass. In a wide range of commercial products for building materials and automotive industry, thermal insulation is improved by the deposition of a continuous nanometric film of Ag which is thin enough to ensure optical transparency but thick enough to reflect infra-red light. The low-emissiv...
Design of multi-layer anti-reflection coating for terrestrial solar panel glass
Published in Bulletin of Materials Science
To date, there is no ideal anti-reflection (AR) coating available on solar glass which can effectively transmit the incident light within the visible wavelength range. However, there is a need to develop multifunctional coating with superior anti-reflection properties and self-cleaning ability meant to be used for solar glass panels. In spite of se...
Low cost fabrication of polymer composite (h-ZnO plus PDMS) material for piezoelectric device application
Flexible piezoelectric composites offer alternative and/or additional solutions to sensor, actuator and transducer applications. Here in this work, we have successfully fabricated highly flexible piezoelectric composites with poly dimethyl siloxane (PDMS) using herbal zinc oxide (h-ZnO) as filler having weight fractions up to 50 wt.% by solution ca...
