Carrier-density dependence of the photoluminescence lifetimes in ZnCdSe/ZnSSe quantum wells at room temperature
(1999)
Photoluminescence lifetimes have been measured at room temperature as a function of carrier
density in ZnCdSe/ZnSSe quantum wells. We show that, at low carrier density (53109?5
31010 cm22), nonradiative recombination ...
Growth of Metal-Phthalocyanine on GaAs(001): an NEXAFS study
(SPIE, 2005)
Organic semiconductors molecules are often employed as a thin film interlayer to improve electronic and optoelectronic devices. The characterisation of the interface is thus important to understand the physical properties ...
Continuous wave MRI diffusion study of water in bentonite clay
(Elsevier, 2005)
A novel NMR technique for imaging materials exhibiting extremely short T2 relaxation times is described and some examples of its application to materials of scientific and industrial interest are presented. The technique ...
Phase breaking in three-terminal contacted single-walled carbon nanotube bundles
(The American Physical Society, 2000)
The three-terminal electrical transport through single-walled carbon nanotube bundles with low resistive
metal contacts is investigated at room temperature. After correcting for the lead resistance, two-probe resistances
close ...

Water vapor on Betelgeuse as revealed by TEXES high-resolution 12 micron spectra
(American Astronomical Society, 2006)
The outer atmosphere of the M supergiant Betelgeuse is puzzling. Published
observations of different kinds have shed light on different aspects of the atmosphere,
but no unified picture has emerged. They have shown, for ...
