Silver has been reported to reduce the transformation temperature of FePt nanoparticles made by both sputtering and chemical synthesis [15, 16]. Furthermore, Ag, MgO and FePt have very similar lattice parameters (aAg = 0.40 nm) and therefore allows for a study of the transformation temperature without destroying the perpendicular texture. Here we describe the study of FePt/Ag multilayers deposited on MgO single crystal substrates at temperatures up to 400 °C. The X-ray diffraction patterns of the (FePt 2 nm/Ag 16 nm) pseudo-multilayers deposited on MgO [001] substrates at different temperatures are shown in Fig. 23. The superlattice (001) peak is present in all samples at temperatures above 280 °C, indicating the formation of Z,lo phase. 

Cerium oxide (CeO ) was deposited onto a (100) LaAlOj single-crystal substrate with a single cube texture and good in- and out-ofplane alignment. A cp scan of the (220) plane of the CeO film yielded a FWHM of 2.45 ° 0.05 ° the rocking curve of the (200) plane indicated a FWHM of 1.688° 0.006°. A layer of YSZ was then deposited by CCVD on top of this ceria layer. The majority of the YSZ deposited as one cube texture (Figure 3) with only a minor 45° film rotation (<1% intensity) present. The... 

These high-performances on single crystal substrates have been confirmed on multicrystalline Si substrates. ANU fabricated a cell of 15.4% efficiency and Voc of 639 mV on a lightly doped substrate and a cell of 15.2% efficiency and Voc of 639 mV on a heavily doped substrate (with no texturing in either case,... 

Here we examine models that try to explain how textures develop during deposition on oriented (single-crystal), textured, polycrystalline, and amorphous substrates. We select electrodeposition of nickel as a model system. 

Boron-doped diamond (BDD) thin films were synthesized at CSEM (Neuchatel, Switzerland) by the hot filament chemical vapor deposition technique (HF CVD) on p-type, low-resistivity (l-3mQcm), single-crystal, silicon wafers (Siltronix). The temperature of the filament was between 2440 and 2560 °C and that of the substrate was monitored at 830 °C. The reactive gas was a mixture of 1% methane in hydrogen, containing trimethylboron as a boron source (1-3 ppm, with respect to H2). The reaction chamber was supplied with the gas mixture at a flow rate of 51 min giving a growth rate of 0.24 pm h for the diamond layer. The obtained diamond film has a thickness of about 1 pm ( 10%) and a resistivity of 15mQcm ( 30%). This HF CVD process produces columnar, random textured, polycrystalline films [9]. 

Seiter et al. [80] found a correlation between the overpotential and growth forms of electrodeposited copper on copper sheet substrate with (100) texture, as shown in Fig. 31. Barnes etal. [81] observed similar results on copper single crystal surfaces near (100) face below 10-mV ridges, 40-70-mV platelets, 70-100-mV blocks and fine platelets and above 100-mV polycrystalline deposit. 

In the past there have been several attempts to investigate the relationship between structure and mechanical properties in polyethylene. It has proved possible to produce samples of the polymer with a single-crystal texture ( ) but they are still polycrystalline and certain ambiguities remain concerning the detailed deformation mechanisms in such samples (9 ). There have also been reports of studies of the deformation of single crystals of polyethylene on extensible substrates (10,11). Because the polymer...
