    Notes: Abstract. Aluminum nitride films of up to 1.2 μm thickness were deposited by excimer laser ablation onto c-, r-, m-, and a-cut sapphire substrates. The films were found to be of (00.1), (11.0), (10.0) and (00.1) orientation on c-, r-, m- and a-cut sapphire substrates, respectively. XRD pole figure measurements showed good in-plane alignment of all three sample sets. AFM measurements reveal that all films were atomically smooth in the initial stages of growth. Furthermore, for AlN(11.0) on r-cut sapphire the film surface remained smooth, with an r.m.s. roughness of about 1 nm up to a film thickness of 1.2 μm. AlN films with the polar c-axis parallel to the film surface are particularly favourable for SAW device applications, since the c-axis direction yields the strongest coupling coefficient. A smooth surface, as for AlN(11.0), is essential to prevent scattering of propagating surface acoustic waves. A SAW r.f. filter was fabricated with interdigital transducers of 5.6 μm wavelength on top of a 1.2 μm AlN(11.0) film on r-cut sapphire. The resonance frequency of 1.068 GHz corresponds well to theoretical expectations for the SAW velocity in this propagation geometry.

    Notes: 4 and disilane Si2H6 induced by continuous wave CO2 laser irradiation has been investigated under the conditions of chemical vapor deposition (CVD) of amorphous hydrogenated silicon a-Si:H. At the very position of depositing the thin film the stationary chemical composition of the processing gas is probed in situ by an effusive molecular beam which passes through a differential pumping stage into a quadrupole mass spectrometer (QMS). With SiH4 as educt and SF6 as a sensitizer, SiH4 and Si2H6 are found in the processing gas while Si3H8 or higher silanes are lacking. Si2H6 and SF6 lead to SiH4, Si2H6, and Si3H8, but higher silanes are missing. The experimentally determined composition of the processing gas is semi-quantitatively reproduced by model calculations based on the assumption of stationary local equilibrium conditions and applying thermodynamic and spectroscopic data (molecular statistics). The mass balance of the processing gas entering and leaving the CVD chamber states an atomic ratio Si:H of 1:2 for the gas phase species forming the solid deposit on the reactor walls. This finding together with theoretical considerations indicates the intermediate Si2H4 to be the dominating gas phase species forming the a-Si:H thin films.

    Notes: Abstract The α-γ angular correlation method has been applied to226Ra and224Ra decays to investigate the hyperfine fields of radon in iron, cobalt and nickel. A random, static quadrupole interaction combined with an aligned magnetic interaction was assumed in the analysis. Gadolinium has also been investigated as a ferromagnetic host, but the oxide layer proved to be too thick.
