Pulsed laser deposition of ZnO thin films decorated with Au and Pd nanoparticles with enhanced acetone sensing performance
M. Alexiadou, M. Kandyla, G. Mousdis +1
We fabricate and compare nanocomposite thin-film ZnO chemoresistive acetone sensors with gold or palladium nanoparticles on the surface, at low operating temperatures. The sensors…
Effects of hydrogen pressure on hydrogenated amorphous silicon thin films prepared by low-temperature reactive pulsed laser deposition
A. Mellos, M. Kandyla, D. Palles +1
We deposit intrinsic hydrogenated amorphous silicon (a-Si:H) thin films by reactive pulsed laser deposition, for various hydrogen pressures in the 0-20 Pa range, at a low depositio…
Hydrogen sensing by sol-gel grown NiO and NiO:Li thin films
I. Sta, M. Jlassi, M. Kandyla +5
Hydrogen sensors have been prepared using nickel oxide (NiO) and lithium-doped nickel oxide (NiO:Li) thin films, deposited on glass substrates by the sol-gel spin coating technique…
Scalable fabrication of nanostructured p-Si/n-ZnO heterojunctions by femtosecond-laser processing
D. G. Georgiadou, M. Ulmeanu, M. Kompitsas +2
We present a versatile, large-scale fabrication method for nanostructured semiconducting junctions. Silicon substrates were processed by femtosecond laser pulses in methanol and a…
Nanocomposite NiO:Pd hydrogen sensors with sub-ppm detection limit and low operating temperature
M. Kandyla, C. Chatzimanolis-Moustakas, M. Guziewicz +1
We present results on the fabrication of chemiresistive nanocomposite NiO:Pd hydrogen sensors, which are able to detect hydrogen concentrations as low as 300 ppb in air, operating…
Nanocomposite NiO:Au hydrogen sensors with high sensitivity and low operating temperature
Maria Kandyla, Christos Chatzimanolis-Moustakas, Elias P. Koumoulos +2
We present results on the development of nanocomposite NiO:Au thin-film hydrogen sensors, which are able to detect hydrogen concentrations as low as 2 ppm in air, operating at low…
Optimized hydrogen sensing properties of nanocomposite NiO:Au thin films grown by dual Pulsed Laser Deposition
I. Fasaki, M. Kandyla, M. G. Tsoutsouva +1
Nanocomposite NiO:Au thin films, formed by gold nanoparticles embedded in a nickel oxide matrix, have been grown by reactive pulsed laser deposition (R-PLD). Two actively synchroni…
Properties of pulsed-laser deposited nanocomposite NiO:Au thin films for gas sensing applications
I. Fasaki, M. Kandyla, M. Kompitsas
Nanocomposite thin films formed by gold nanoparticles embedded in a nickel oxide matrix have been synthesized by a new variation of the pulsed laser deposition technique. Two activ…
