A memory capacitor with a multistacked tunnel layer of Al2O3/HfO2/SiO2 (AHO) has been fabricated together with HfO2 charge trapping layer and Al2O3 control oxide layer. The resulting capacitor exhibits a memory window as large as 7.6 V for +/- 12 V sweep v ...
This paper describes a heterogeneous oligonucleotide-hybridization assay based on hot electron-induced electrochemiluminescence (HECL) of a rhodamine label. Thin oxide-film coated aluminum and silicon electrodes were modified with an aminosilane layer and ...
Using a density functional scheme, the authors investigate the electronic properties of an epitaxial silicon oxynitride layer on a 6H-SiC(0001) surface, as recently realized experimentally. Simulated scanning-tunneling-microscopy images of filled and empty ...
Al2O3 films are grown by atomic layer deposition (ALD) using trimethylaluminum and water as precursors on HF-last and NH3 plasma pretreatment Si substrates. The thickness, surface roughness, and density of Al2O3 films as well as the nature of their interla ...
The structure of anodized nanoporous alumina is described as a closely-packed hexagonal arrangement of monodispersed nanopores, of which size and interval can be controlled by changing the anodization conditions. Nanoporous alumina thin films with highly o ...
In the bauxite refining Bayer’s process, about 8 x 107 t/y of problematic residue is produced worldwide by extraction of alumina from bauxite earth. The bauxite refining industry requires strategies for rehabilitation of residue deposits to comply with leg ...
We describe a new low-cost technique for continuous monitoring of the thickness of biofilms and tissue cultures, and we demonstrate the advantage of using electrodes of different dimensions to probe different depths of a sample. We have used electric imped ...
We present a unique probe that is based on a quartz tuning fork and a microfabricated cantilever. The probe is self-actuating and self-sensing. The cantilever can be tailored to the needs of specific applications, in this case to feature an electrically co ...
We report the preparation and magnetic properties of Co2FeO4nanowires grown by electrodeposition inside the pores of anodic aluminum oxide (AAO). The synthesis requires two successive steps: the electrodeposition of fairly amorphous Fe-Co oxides or hydroxi ...
Organic-inorganic hybrid coatings are becoming increasingly important due to their unique property combination [1, 2], including high optical transparency, improved scratch and abrasion resistance and excellent weathering, thanks to the synergism between t ...
