WebTaking SiC as an example, we investigate the effect of surface polarity on the wetting behavior by water using experiments and molecular dynamic simulations. It is found that the contact angle (CA) of deionized water on the carbon-face (C-face) is significantly larger than that on the silicon-face (Si-face) for both 6H-SiC and 4H-SiC, while the CA of …
WebThe etch rate of aqua Regia for gold is approx. 10 μm/min (at room temperature) and can be increased to several 10 μm/min at elevated temperatures. Palladium, aluminium, copper and molybdenum are also etched at room temperature in aqua regia. For etching platinum or rhodium, the etching solution has to be heated to attain a reasonable etch rate. dobereiner arranged the elements by triadsWebdent etch rate enabled anisotropic wet etching, which results in structures that are bounded with slow etch planes. For example, the etch rate of Si(111) in KOH solution can be over two orders of magnitude slower than Si(110); therefore Si(110) surface can be etched to produce deep trenches with (111) sidewalls [1].
