Hall electrical properties measured by the van der Pauw method and low-temperature photoluminescence (77 K PL) spectra of pseudomorphic GaAs/InyGa1-yAs/AlGaAs modulation-doped field-effect transistor-type heterostructures grown by molecular-beam epitaxy we ...
Thin hydrogel barriers formed on the inner surface of injured arteries by interfacial photopolymerization dramatically reduced thrombosis and intimal thickening in rat and rabbit models of vascular injury. This polymerization technique allowed the synthesi ...
Automated shading systems have the potential to exploit daylight in buildings to save energy of artificial lighting and cooling loads and improve occupants'f visual comfort. This paper investigates the daylighting performance of automated Venetian blinds b ...
This paper evaluates the influence of light levels (i.e., illuminance) on subjective thermal perception of people, distinguishing between thermal sensation and thermal evaluation. The goal is to investigate whether reported effects found by other studies i ...
Highly accurate group delay measurements in long single-mode fibers were achieved over the full 1200-1600 nm spectral range by measuring phase shifts of a modulated lightwave. The high modulation frequency is shifted down to the kilohertz range using a sec ...
The molecular-beam epitaxial growth conditions of (N + 1)(InAs)m/N(GaAs)n short period superlattices (SPSs) on GaAs substrates have been optimized. Hall electrical properties measured by the van der Pauw method were compared to low-temperature photolumines ...
We investigated the adsorption properties of methanol and ethanol on Si(111)2 x 1 as a function of temperature in the range 80-300 K by means of synchrotron radiation photoemission of core and valence levels. A physisorbed state is characterized at 80 K, w ...
A new technique for single-mode fibers chromatic dispersion measurements using phase-shift measurements is presented. The poor dynamic range and the perturbation of the rf interferences are the main drawbacks of the well-known method using a LED filtered b ...
Sn and Pt films were laser deposited on a quartz plate or C membrane supports by using light-induced thermal dissocn. and photodissocn. of SnMe4 and bis(hexafluoroacetylacetonato)platinum, resp. An Ar laser (l = 514.5, 455.5, 257.3 nm) and a Hg lamp (l = 2 ...
