Optical, electrical and structural characterization of chloridedoped ZnO nanopillars obtained by electrodeposition

As-grown and chloride-doped ZnO nanopillars were electrodeposited onto bareFTO/glass and ZnO-compact layer/FTO/glass substrates. To analyse the effect of the presence of chloride ions in the electrolytic bath, NH4Cl was progressively added up to 0.02 mol L-1. As preliminary examination, the morphology of ZnO nanostructures was analysed by SEM micrographs and chlorine incorporation was detected by EDS. Then, a detailed analysis comprising structural, electrical, optical and defect properties was constructed using XRD, electrical resistance measurements and UV-Vis-IR spectroscopy. As the chlorine concentration in the film increases, XRD reveals a displacement of diffracted planes due to macrostrain of the ZnO lattice and the electrical resistance diminishes. Also, the UV optical absorption edge shifts to higher energies due to Moss-Burstein effect which corresponds to electron densities in the order of 1 to 6 x 1019 cm-3, and the infrared spectra reveal the presence of free electrons, allowing a moreprecise determination of the free electron densities.Fil: Berruet, Mariana.

Sizing up entanglement in mutually unbiased bases with Fisher information

We present a single-shot method for phase recovery based on the transport of irradiance equation (TIE). The system utilizes a beamsplitter and mirrors to achieve two simultaneous (laterally separated) images with different defocusing degrees, which are acquired with a digital camera. The proposed method provides a simple achromatic system for one-shot phase imaging with potential application for phase recovery of dynamic samples. Validation experiments are presented.
