Switchable Electric Field Induced Diode Effect in Nanostructured Porous Silicon
(Institute of Electrical and Electronics Engineers, 2013-04)
Unidirectional current flow (diode-like behavior) is observed in Al/Nanostructured Porous Silicon/Al structures (Al/SP/Al) after applying a forming electric field (E) for a long time. We found that rectifying characteristics ...
Negative differential resistance in porous silicon devices at room temperature
(Elsevier, 2014-12)
We report a voltage controlled negative differential resistance (NDR) effect at room temperature in two types of devices based on porous silicon (PS): thermally oxidized porous silicon multilayer with Ag electrodes in a ...
The Origin of the Studies on the Comedy as Genre in Hellenistic Times and Its Influence on Later Periods (1st Century BC - 10th Century AD)El surgimiento de los estudios sobre el género de la comedia en época helenística y su influencia en periodos posteriores (s. I a.C. -X d.C.)

Internal Strain Distribution in Freestanding Porous Silicon
(Electrochemical Society, 2009-12)
Elastic properties of freestanding porous silicon layers fabricated by electrochemical anodization were studied by Raman scattering. Different anodization currents provided different degrees of porosity in the nanometer ...

White light from annealed porous silicon: Broadband emission from violet to the near infrared
(Elsevier Science, 2015-03)
We report white light emission under UV excitation from porous silicon (PS) samples annealed at different temperatures and surrounding atmospheres. The photoluminescence (PL) spectra show a broad emission from ultraviolet ...
On the origin of white photoluminescence from ZnO nanocones/porous silicon heterostructures at room temperature
(Elsevier, 2014-12)
ZnO nanocones were grown on porous silicon (PS) by vapor transport at different temperatures and O2 flow rates without metal nanocatalysts. The ZnO/PS heterostructures were studied by electron microscopy, and by photoluminescence ...
