This paper describes a method of thin film and MEMS processing which uses self-assembled monolayers as ultra-thin organic surface coating to enable a simple removal of microfabricated devices off the surface without wet chemical etching. A 1.5-nm thick self-assembled monolayer of dodecyltrichlorosilane reduces the adhesion between the SiO substrate surface 2 and a 100-nm thick evaporated alumin...

In this work, the composition of zinc–aluminum–magnesium alloy coating was designed to have a fixed aluminum–magnesium ratio 1:1, while content aluminum and magnesium elements increases gradually within range 1–2 wt.%. The micro-morphology with different compositions observed by scanning electron microscope (SEM). Combined surface distribution results energy dispersive spectrometer (EDS) analys...

The nanostructuring of silicon surfaces--known as black silicon--is a promising approach to eliminate front-surface reflection in photovoltaic devices without the need for a conventional antireflection coating. This might lead to both an increase in efficiency and a reduction in the manufacturing costs of solar cells. However, all previous attempts to integrate black silicon into solar cells ha...

The synthesis of polyaniline- Fe2O3 nanocomposite coating on aluminum Alloy 5052 (AA5052) surface has been investigated by using the galvanostatic method. The anticorrosion performance of polyaniline-Fe2O3 coating was investigated in 3.5% NaCl solution by the open- circuit potential (OCP), Tafel polarization technique and Electrochemical Impedance Spectroscopy (EIS). The corrosion rate of polya...
