Temperature dependences of fibre-optical sensors of mechanical values
Tập 1 - Trang 3 pp. - 2002
In the work the temperature dependences of the fibre-optical sensor of
mechanical values are explored. The examinations of influence of temperature
changes on the transmitting characteristic of FOS were spend. As a sensing
device the silicon membrane with width h1=40 micron with strong centre by width
h3=200 micron was used. The measuring were spend at temperatures T1=20/spl
deg/C, T2=60/spl deg/C...

The device of digital data processing from the fibre-optical sensor of mechanical values
Tập 1 - Trang 2 pp. - 2002
In the work the creation of the device of digital signal processing from the
fibre-optical sensor of mechanical values is featured. The device allows to
spend measurements and to produce adjustment of the sensor remotely and with a
big degree of accuracy. The device connects to a PC on a three-wire line of link
with usage of the standard transfer protocol of data RS-232C. The scheme is
implemented...

Tunneling of electrons through heterostructures with quantum rings in a magnetic field
Tập 1 - Trang 3 pp. - 2002
Tunneling current of electrons through a quantum ring placed in a barrier of
InAs/GaAs in the presence of Aaronov-Bohm magnetic flux is calculated. It is
shown that tunneling current has oscillation behavior in dependence on magnetic
flux through the quantum ring. It is considered two cases: solenoid model and
uniform magnetic field one. In the second model tunneling current of electrons
is aperio...

Simulation of initial stages of Ge nano-island nucleation on Si (111) surface
Tập 1 - Trang 3 pp. - 2002
Reasons of three-layer Ge island nucleation on Si(111) surfaces at low
deposition rate at the initial stages of wetting layer formation were
investigated. Simulation of Ge epitaxial growth on atomically clean and flat
Si(111) surface was carried out by 3D Monte Carlo model. If the activation
energy of heterodiffusion of adsorbate along the substrate is less than
homodiffusion energies of the adsor...

Visible photoluminescence from Si nanocrystals fabricated in SiO/sub 2/ films after annealing under hydrostatic pressure
Tập 1 - Trang 3 pp. - 2002
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
the photoluminescen...
