    Variation of Charge Transfer in Zn-naphtholimines with TCNQ (1999)
    Springer
    Molecular engineering 8 (1999), S. 411-417

    ISSN: 1572-8951
    Keywords: Charge transfer complex ; Zn[RNAFIN]2 with TCNQ ; vibrational spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Abstract The charge transfer in charge transfer complexes, based on Zinc-naphtholimines (Zn[RNAFIN]2) with TCNQ is studied in the present paper. New electronic states form with the effect of corresponding transition bands in vibrational spectra. This proves the existence of mixed valence complexes. Band peak shifts in the visible spectral region are manifest, which provide for the evaluation of the charge transfer (CT). In this work the CT is calculated by use of the C≡N stretch band shift.Due to this results, we prove that an increase of the ligand volume of the donor (RNAFIN) abates the degree of charge transfer.

    Tensile Stress in Nanometre Thick MBE Grown CaF2 on (111) Si (1999)
    Springer
    Molecular engineering 8 (1999), S. 403-409 
    Details
    ISSN: 1572-8951
    Keywords: Molecular interface structure ; molecular beam epitaxy ; tensile stress ; epitaxy heterosystem ; Silicon-on-Insulator
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract CaF2 epitaxial layers were prepared by MBE and investigated by RBS and ion channeling measurements. Films of about 30 nm thickness were found to be strained by tensile stress causing a rhombohedral symmetry of the layers. These results are interpreted in terms of the different thermal expansion coefficients of substrate and deposit, respectively.
