Conductivity fluctuations in proton-implanted ZnO microwires
B. Dolgin, I. Lorite, Y. Kumar +4
The electric noise can be an important limitation for applications of conducting elements of size in the nanometer range. The intrinsic electrical noise of prospective materials fo…
Study of the Negative Magneto-Resistance of Single Proton-Implanted Lithium-Doped ZnO Microwires
I. Lorite, C. Zandalazini, P. Esquinazi +14
The magneto-transport properties of single proton-implanted ZnO and of Li(7\%)-doped ZnO microwires have been studied. The as-grown microwires were highly insulating and not magnet…
Aluminium as catalyst for ZnO nanostructures growth
C. Zandalazini, M. Villafuerte, M. Oliva +1
We report the growth of Al-catalysed ZnO nanowires (NWs) using a thermal evaporation technique.Before the growth, the substrates were covered with a distribution of Al nano-island…
The convergence method to calculate particles fluxes in x rays spectrometry techniques. Application in nuclear compounds
C. Figueroa, N. Nieva, H. Brizuela +1
A method to calculate particle fluxes applicable in most of the spectroscopy techniques is described. Flux intensities of backscattered or absorbed electrons and emitted photons ar…
Evidence of defect-induced ferromagnetism in ZnFeO thin films
C. E. Rodríguez Torres, F. Golmar, M. Ziese +2
X-ray absorption near-edge and grazing incidence X-ray fluorescence spectroscopy are employed to investigate the electronic structure of ZnFeO thin films. The spectrosc…
ZnO:Co Diluted Magnetic Semiconductor or Hybrid Nanostructure for Spintronics?
F. Golmar, M. Villafuerte, A. Mudarra Navarro +4
We have studied the influence of intrinsic and extrinsic defects in the magnetic and electrical transport properties of Co-doped ZnO thin films. X ray absorption measurements show…
Convergence method for calculating solutions to the 3D invariant embedding integro-differential equations describing electron transport processes
Carlos Figueroa, Horacio Brizuela, Silvia P. Heluani
The electron and photon transport processes in spectroscopy techniques described by the invariant embedding theory is here revisited. We report a convergence method to obtain close…
Changes in the electrical transport of ZnO under visible light
S. Dusari, J. Barzola-Quiquia, P. Esquinazi +1
Complex impedance spectroscopy data in the frequency range 16Hz < f < 3 MHz at room temperature were acquired on pure ZnO single crystal and thin film. The measured impedance of th…
