Nanostructured BiVO4 Photoanodes Fabricated by Vanadium-infused Interaction for Efficient Solar Water Splitting
Amar K. Salih, Abdul Zeeshan Khan, Qasem A. Drmosh +5
Bismuth vanadate (BiVO4) has emerged as a highly prospective material for photoanodes in photoelectrochemical (PEC) water oxidation. However, current limitations with this material…
Kinetics of charge carrier recombination in beta-Ga2O3 crystals
T. T. Huynh, L. L. C. Lem, A. Kuramata +2
Cathodoluminescence spectra were measured to determine the characteristics of luminescence bands and carrier dynamics in beta-Ga2O3 bulk single crystals. The CL emission was found…
Red Luminescence in H-doped beta-Ga2O3
Thanh Tung Huynh, Ekaterine Chikoidze, Curtis P. Irvine +8
The effects of hydrogen incorporation into beta-Ga2O3 thin films have been investigated by chemical, electrical and optical characterization techniques. Hydrogen incorporation was…
Enhancement of the UV emission from gold/ZnO nanorods exhibiting no green luminescence
Saskia Fiedler, Laurent O. Lee Cheong Lem, Cuong Ton-That +2
Large reflection losses at interfaces in light emitting semiconductor devices cause a significant reduction in their light emission and energy efficiencies. Metal nanoparticle (NP)…
The role of surface depletion layer effects on the enhancement of the UV emission in ZnO induced by a nanostructured Al surface coating
Saskia Fiedler, Laurent O. Lee Cheong Lem, Cuong Ton-That +1
The UV enhancement of Al-coated ZnO single crystals with a wide range of carrier densities is systematically studied using depth-resolved cathodoluminescence (CL) and photoluminesc…
Correlative Study of Enhanced Excitonic Emission in ZnO Coated with Al Nanoparticles using Electron and Laser Excitation
Saskia Fiedler, Laurent O. Lee, Cheong Lem +4
Metal nanoparticle (NP) surface coatings are known to significantly enhance the ultra-violet luminescence intensity of ZnO. Although there is general agreement that resonantly exci…
Shallow carrier traps in hydrothermal ZnO crystals
C. Ton-That, L. L. C. Lem, M. R. Phillips +5
Native and hydrogen-plasma induced shallow traps in hydrothermally grown ZnO crystals have been investigated by charge-based deep level transient spectroscopy (Q-DLTS), photolumine…
Coalescence of ZnO nanowires grown from monodispersed Au nanoparticles
Liangchen Zhu, Matthew R. Phillips, Cuong Ton-That
New insights into controlling nanowire merging phenomena are demonstrated in growth of thin ZnO nanowires using monodispersed Au colloidal nanoparticles as catalyst. Both nanowire…
Molecular nitrogen acceptors in ZnO nanowires induced by nitrogen plasma annealing
C. Ton-That, L. Zhu, M. N. Lockrey +8
