چکیده
Using the methods of Auger electron and photoelectron spectroscopy light absorption spectroscopy, composition, densities state electrons in valence band, parameters energy bands Ge (111) implanted with Na + ions an E 0 =0.5 keV at a dose D sat =6· 10 16 cm -2 thin layer NaGe 2 obtained by annealing ion-implanted Ge. It is shown that narrow n-type band (~ 0.2 eV) appears spectrum after ion implantation near bottom conduction which explained presence large number unbound atoms layer. nanofilms gap ~ 0.45 eV was for first time Keywords: nanostructure, photoelectrons, spectrum, hybridized states, densities, implantation.

The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...

Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects built on conventional SiO2/Si substrates reveal the breakdown current density on the order of 1 μA/ nm (i.e., 10 A/cm), which is ∼100× larger than the fundamental limit for the metals but still smaller than the maximum a...
