2 O3(100) substrates. We also produced free-standing NiTi films by deposition on KBr substrates and subsequent substrate removal
by immersion in water. The presence of the solid-solid phase transformation responsible for the shape memory effect has been
demonstrated through temperature-dependent X-ray diffraction and four-probe resistance versus temperature measurements. On
cooling the deposited film, the austenite-martensite transformation was measured at around 195 K; on heating the film the
reverse transformation was around 250 K. Evidence of the shape-memory effect for free-standing films was obtained in a bending
deformation-shape recovery experiment.

2 ; for 100 fs pulses from the same laser the experimental threshold was at 1.5 J/cm2. Histopathological examinations and scanning electron micrographs confirm the high quality of the excisions. No sign of significant
thermal damage was observed.

2 O3, AlN and Si substrates produced by vacuum ultraviolet induced decomposition of palladium acetate is described. The palladium
films formed and the palladium acetate layers used were characterised by using ultraviolet spectrophotometry and Fourier transform
infrared (FTIR) spectroscopy. The optical transmission of the films after irradiation with pseudo-continuous 126 nm radiation
generated by an excimer lamp provided information about the decomposition rate at different pressures and exposure times.
The FTIR spectra recorded the chemical changes of the C=O, COO- and CH3 groups at different exposure times. The decomposition mechanism of the palladium acetate under these conditions appears to
be quite different to that induced by pulsed laser irradiation.

Based upon the hidden Lie SU(1,1) symmetry, we have constructed the unitary decoupling transformation which diagonalizes the
multimode two-quantum Jaynes-Cummings model and provides us with an extremely convenient basis to gain a deeper understanding
of the dressing processes present in the matter-field interaction. This canonical transformation approach is very simple and
can be easily extended to other generalized Jaynes-Cummings models.

2 radicals when the 355 and 1064 nm outputs of a Nd:YAG laser were applied. While for the 532 nm ablation, a relatively higher
concentration of excited atomic carbon was obtained. Different Raman and FTIR spectral features were observed from the deposited
films with different ablation wavelengths. The 532 nm laser ablation is proposed for the synthesis of high quality carbon
nitride films.

Experimental observations in certain rare earth nuclei have established the presence of sizeable B(M1) strength of two peak
structure lying in the 5–10 MeV region. The character of the states concerned, studied within a self-consistent Random Phase
Approximation using Skyrme forces, are identified to be that of proton and neutron giant spin-flip resonances.

2 (2 mm thick) and GaSe (1 mm thick) crystals are applied as nonlinear media. GaSe has a larger tuning range and is more efficient
in the whole spectral range than AgGaS2. The average IR power reaches up to 2.0 mW at 8.5 μm when the GaSe crystal is used, and up to 1.3 mW at the same wavelength
when AgGaS2 is applied for the frequency conversion.

For the first time direct contamination-free transfer to UHV was achieved for the P-rich InP(100) surface that is the easiest
to prepare and control in the MOCVD environment. To avoid contamination during transfer a commercial MOCVD apparatus was modified
to allow for transfer of samples to the 10-9 mbar UHV range within a very short time (less than 20 s) [1]. Epitaxial InP(100) films were prepared with TBP (tertiarybutylphosphine)
and TMIn (trimethylindium) as precursors. In situ reflectance anisotropy spectroscopy (RAS) was carried out in the MOCVD environment.
After transfer of the sample to UHV the same RAS spectrum was recovered. Auger-electron spectra (AES) confirmed the P-termination
of the surface reconstructions suggested by RAS.

Synthesis, integration, and electrical properties of individual single-walled carbon nanotubes 总被引:4,自引:0,他引:4

High-quality single-walled carbon nanotubes (SWNTs) are synthesized by chemical vapor deposition (CVD) of methane on silicon-dioxide
substrates at controlled locations using patterned catalytic islands. With the synthesized nanotube chips, microfabrication
techniques are used to reliably contact individual SWNTs and obtain low contact resistance. The combined chemical synthesis
and microfabrication approaches enable systematic characterization of electron transport properties of a large number of individual
SWNTs. Results of electrical properties of representative semiconducting and metallic SWNTs are presented. The lowest two-terminal
resistance for individual metallic SWNTs (≈5 μm long) is ≈16.5 kΩ measured at 4.2 K.
