The effect of the number of carbon atoms in a carbon-bearing precursor molecule on the crystallite size in diamond films grown on silicon substrates by microwave plasma-enhanced chemical-vapor deposition is investigated. It is shown that the crystallite size decreases with increasing number of carbon...

pis the number ofdouble bondsandqis the number of carbon atoms from the double bond in the terminal region of the molecule. C 18:1 (n-9), for instance, is 9-octadecenoic acid (one double bond in 9 position from terminal side of molecule). The relation between the systematic name, the...
Very high angle (~100 mrad) annular dark-field (HAADF) images in a dedicated scanning transmission electron microscope (STEM) can be used to quantitatively measure the number of atoms in a cluster on a support material. We have developed a computer program which will automatically find the loca...
