This paper reports the research results of the effect of cathode shape during vertical buffered electropolishing (BEP) by employing a demountable single cell niobium (Nb) superconducting radio frequency (SRF) cavity. Several different cathode shapes

Large area dimer vacancy arrays can be formed on the Si(100) surface when Si atoms are deposited on the Si(100)-2×1 surface followed by quenching from 1200°C. The dimer vacancy lines (DVLs) of the dimer vacancy array run perpendicular to the dimer

Two kinds of regular defects have been observed in our experiments. One kind is caused by losing or inserting adatom rows between two domain boundaries. The other is caused by losing or inserting adatom rows between two domain boundaries, while one d

The binding energy of a condensed system in the form of the semi-empirical tight-binding (SETB) approximation is expanded in individual terms, each corresponding to an atom. We find that these binding energy terms agree surprisingly well with the sit

The scanning tunnelling microscope (STM) has been employed to fabricate grooves by extracting Si atoms out of the Si(111)-7×7 surface and deposit the Si atoms back onto the Si(111)-7×7 surface at room temperature. The deposited Si atoms can form a

Scanning tunneling microscopy (STM) was used to characterize the surface topography of polyacrylonitrile (PAN)-based carbon fibers before and after electrochemical treatment, stretch resistance test, and high-temperature treatment. A new kind of spir
