An alternative fluorine precursor for the synthesis of SnO2:F by spray pyrolysis
FLEISCHER, KARSTEN; ARCA, ELISABETTA; SHVETS, IGOR (2012)An alternative, non-toxic precursor was employed for the synthesis of SnO2:F transparent conducting oxide. The performance of benzenesulfonyl fluoride (BSF) as F source for spray pyrolysis was investigated. Its decomposition ... -
Aluminium doped Zn1−xMgxO A transparent conducting oxide with tunable optical and electrical properties
FLEISCHER, KARSTEN; SMITH, CHRISTOPHER; SHVETS, IGOR; ARCA, ELISABETTA (2012)A ternary mixed oxide Zn1 xMgxO has been doped with aluminium to create a range of transparent conducting oxides with tunable refractive index as well as work function. Conductive material was synthesised up to a magnesium ... -
Effect of Chemical Precursors On the Optical and Electrical Properties of p‐Type Transparent Conducting Cr2O3:(Mg,N)
FLEISCHER, KARSTEN; ARCA, ELISABETTA; SHVETS, IGOR (2013)Cr2O3:(Mg,N) has been reported as a p-type transparent conducting oxide. In this contribution the effect of each precursor used for the deposition by spray-pyrolysis, will be explored and their role in determining the ... -
Improving solar cell efficiency with optically optimised TCO layers
FLEISCHER, KARSTEN; SHVETS, IGOR; ARCA, ELISABETTA (2012) -
Influence of the Precursors and Chemical Composition of the Solution on the Properties of ZnO Thin Films Grown by Spray Pyrolysis
SHVETS, IGOR; FLEISCHER, KARSTEN; ARCA, ELISABETTA (2009) -
Magnesium, nitrogen codoped Cr2O3: A p-type transparent conducting oxide
FLEISCHER, KARSTEN; ARCA, ELISABETTA; SHVETS, IGOR (2011)A p-type transparent conductive oxide (TCO) was synthesised by codoping of poorly conducting chromium oxide (Cr2O3) with magnesium and nitrogen. We demonstrated that the codoping produced a TCO with good figure of merit ... -
Numerical investigation of the stability of Ag-Cu nanorods and nanowires
SHVETS, IGOR; ARCA, ELISABETTA (2008)Molecular dynamics simulations have been employed to investigate thermally-induced phase separation processes in nanometer-sized Ag50 Cu50 rods and wires. In the absence of concentration gradients, the mechanism underlying ... -
Raman spectra of p-type transparent semiconducting Cr<inf>2</inf>O<inf>3</inf>:Mg
SHVETS, IGOR; FLEISCHER, KARSTEN; CAFFREY, DAVID; FARRELL, LEO; NORTON, EMMA; MULLARKEY, DARAGH; ARCA, ELISABETTA (2015)Abstract We present an analysis of the Raman spectra of p-type transparent conducting Cr2O3:Mg grown by various techniques including spray pyrolysis, pulsed laser deposition, molecular beam epitaxy and reactive magnetron ... -
Tuning the crystallographic, morphological, optical and electrical properties of ZnO:Al grown by spray pyrolysis
ARCA, ELISABETTA; SHVETS, IGOR; FLEISCHER, KARSTEN (Elsevier B.V., 2014)In this contribution the effect of different deposition conditions on the physical properties of ZnO:Al grown by spray pyrolysis is outlined. In particular, it will be shown that the solvent composition affects the ...
