Amorphous carbon nitride (a-CN x ) films have rather high resistivity and low dielectric constants that could be applied as low dielectric constant materials. Several properties of a-CN x films including interactions with metal electrodes are studied and discussed using data from the frequency dependence of capacitance, Raman and photoluminescence spectra.
Atomic scale extraction of hydrogen atoms on Si(001)-(2 1)-H and -(3 1)-H surfaces between 300 and 610 K have been studied using a scanning tunneling microscope. Hydrogen atoms were extracted at positive and negative sample bias voltage. Site-selective desorption and reconstruction from the dihydride phase to the monohydride phase are found in the desorption of hydrogen atoms from Si(001)-(3...
