Etched tracks have recently come into the focus of renewed interest, as it has
turned out that they have a great future application potential. Therefore it is
worthwhile to review the techniques for ion track characterization. Especially,
ion transmission spectrometry (ITS) has recently emerged as a new tool for the
rapid characterization of both the average diameter and the shape of etched
tracks... hiện toàn bộ

X-ray spectroscopic study of carbon produced at destruction of field cathodes from carbon nanotubes Tập 1 - Trang 2 pp. - 2002
A.V. Gusel'nikhov, P.A. Pruss, A.V. Okotrub
The opportunity for measurement of X-ray spectra with the help of carbon
nanotubes cathode was realized. The K/spl alpha/-spectra of the carbon, which
was transferred on the copper anode as a result of field emission from cathodes
containing multiwall and single-wall carbon nanotubes, was obtained. The carbon
materials were found to consist from graphite-like particles. The spectrum of
carbon mate... hiện toàn bộ

Visible photoluminescence from Si nanocrystals fabricated in SiO/sub 2/ films after annealing under hydrostatic pressure Tập 1 - Trang 3 pp. - 2002
K.S. Zhuravlev, I.E. Tyschenko, E.N. Vandyshev, N.V. Bulytova, A. Misiuk, L. Rebohle, W. Skorupa
The effect of hydrostatic pressure applied at high temperature on
photoluminescence of Si-implanted SiO/sub 2/ films has been studied. For the
films implanted with Si/sup +/ ions to total doze of 4.8 /spl middot/ 10/sup 16/
cm/sup -2/ a high temperature annealing (T/sub a/=1 000/spl deg/C) under high
hydrostatic pressure (12 Kbar) causes a "blue" shift and increase intensity of

Surface structure and optical properties of Ti-diffused LiNbO/sub 3/ waveguides Tập 1 - Trang 2 pp. - 2002
I.E. Kalabin, T.I. Grigorieva, L.D. Pokrovsky, D.V. Sheglov, D.I. Shevtsov, V.V. Atuchin
The topmost surface of crystal during Ti-indiffused LiNbO/sub 3/ waveguide
preparation was studied using atomic force microscopy and high energy electron
diffraction. The formation of the flat terraces with height step /spl sim/0.24nm
as a result of high temperature annealing has been detected. The global changing
of surface morphology induced by Ti diffusing was observed. No new phase
