A novel p-type hydrogenated chlorinated nanocrystalline silicon (nc-Si:H:(Cl)) film was fabricated from chlorinated materials, i.e., SiH2Cl2 and SiCl4,by rf plasma-enhanced chemical vapor deposition. These p-type nc-Si:H:(Cl) films showed high conductivities of 10–50 S/cm under 3000–5000 ppm B2H6-mixing concentrations with lower optical absorption in the visible region, while maintaining a high film crystallinity. No marked darkening of the ZnO:Al layer was observed after deposition of the p-type nc-Si:H:(Cl) layer fabricated from SiH2Cl2 and SiCl4 compared to the p-type Si:H film fabricated from SiH4. The origin of the low optical absorption in p-type nc-Si:H:(Cl) is demonstrated along with the performance of a p–i–n structure amorphous silicon solar cell.

poly-BIS (THI OCYANATO-N)BI S-#-( 1,2,4-TRIAZ OLE-N2,N4)-IRON (II)the most acceptable explanation for the line-broadening in the M6ssbauer quadrupole doublet already mentioned, the measurements are clearly in favour of possibility (ii).To verify this, we also performed M6ssbauer measurements on [Zn(trz)2(NCS) 2] doped with approximately 0.1% 5VFe. The Zn compound does not show disorder and although it crystallizes in a different space group (Pben), the site symmetries of the metal ions are the same in both compounds. Despite the poor statistics of the spectrum, no significant line-broadening was observed. The above results justify the conclusion that the trz rings are orientated in a random way.No evidence for disorder, such as streaks or diffuse reflections, could be observed in X-ray photographs. This may be due to the high background level, caused by the Cu Ka radiation used.Finally we mention that, because the degree of disorder in [Fe(trz)2(NCS) 2] differs significantly from 50%, we have re-examined our results on the corresponding Co compound. In a previous paper (Engelfriet et al., 1979) we assumed the degree of disorder in the Co compound to be 50%. The occupation rate of one of the enantiomorphs was found to be 42 (1)%. However, refinement of all parameters together with the occupation rate did not produce significant changes in the R factors and the positional parameters. Introduetlon. This is part of a series of structural investigations on the Ni n halide complexes containing the title macrocyclic ligand, hereafter abbreviated as meso-Me6[ 14]aneN 4. A main feature of interest in these studies is a clarification of the dispositions of water molecules around a Ni n ion and thereby to explain the role played by water in the spin-state variations among the Ni n complexes. The crystal structures of the two complexes formed with NiC12 and the title ligand, which are the low-spin four-coordinate complex aneN4)]C12.2H20 and the highspin six-coordinate complex aneN4)]. 2CHC13, have been reported (Ito & Toriumi, 1981). In this paper the structure of the title complex [NiF2 aneN4)].5H20 is described. The compound was prepared from the corresponding perchlorate salt aneN4)](C104) 2 (Warner & Busch, 1969) by ion exchange (Dowex 1X8). Slow evaporation of the eluate from the column yielded triclinic single crystals. A pale-violet plate was shaped into an approximate sphere with a diameter of 0.40 mm. X-ray diffraction data were measured on a Rigaku AFC-5 four-circle diffractometer with graphite° monochromatized Mo Ka radiation. Within the range 20 _< 60 °, 5958 independent reflexions with I Fol >_ 3tr(IF o I) were obtained. The intensities were corrected for Lorentz and polarization factors, but no absorption correction was applied.
