Raman investigations show that two different types of material can be obtained: either a purely amorphous one for hydride concentrations not exceeding 10% or a mixture of Si submicrocrystals embedded in an amorphous medium for the higher concentrations. Given the conditions of the growth technique ...
In the last years, vis–NIR spectroscopy along with micro-Raman spectroscopy and X-ray powder diffraction (XRPD) has also been successfully exploited for the study of the stoichiometry and crystalline structure of cadmium yellows (CdS and Cd1−xZnxS), a class of pigments known for their ...
The photoproducts were studied by clectronic and resonacnce Raman Spectroscopy. The high specificity of resonance Raman spectroscopy was used to characterize different photoproducts at concentrations of the order uf 10−5 m, present simultaneously in the same mixture. The results show that a ...
Raman spectra are memorized onto the target of the camera detection head of a modified CODERG UF 76 multichannel spectrometer. To process the spectral information each spectrum is digitized over 500 points and transferred to a PDP 11 minicomputer by a home-built line integrating video digitizer; ...
Relatively low-frequency acoustic Raman active modes at νa∼30 sm− 1 of whispering gallery mode are known to excite under microwave irradiation at νR frequency [9]. If then NT to place in resonant magnetic field, when cyclotron diameter is equal to NT diameter, dc = d, so the Larm...
(b) An optical microscope image of a device withs = 1μm gap is shown. (c) Representative I-V characteristics from devices on die 2 after high temperature flash annealing are shown. The shorted (control) wire clearly shows a Ohmic behavior. The device withs = 1 μm spacing...

FT-IR, Raman, NMR, UV-Vis Spectroscopy, X-ray diffraction, and scanning electron microscopy studies were used to investigate the structural, optical, and morphological features of the metal free catalysts. We have constructed COPs with a π-electron deficient (Lewis acidic) triazine core and π...
A graphene interface junction,formed by single and bi-layer graphene (G1/G2)as shown in Fig.1(c),will give rise to opposite signs of PC for the two different mechanisms.Thus it provides a unique opportunity to identify the ori-gin of PC.Since single-layer graphene has a linear energy-...
