摘要
Nanophases and films of SiO2 and metal silicides are obtained by the low-energy (E-0 = 1-5 keV) implantation of O-2(+), Ba+, Cu+ and Co+ ions followed by annealing on the surface of a free Si/Cu (100) nanofilm system. Their surface morphology, composition, energy-band parameters, the maximum value of the secondary-electron-emission coefficient, and the quantum yield of photoelectrons are determined. It is shown that the band gap of metal silicides is 0.3-0.4 eV, and their specific resistance is 100-500 mu Ohm cm.
