    Notes: In this work ballistic electron emission microscopy was used to probe on nanometer scale the local Schottky barrier height in metal-semiconductor (MS) contacts with an intentionally inhomogeneously prepared metallization. Schottky barrier maps of heterogeneous Au/Co/ GaAs67P33(100)-Schottky contacts show areas with different barrier heights which can be correlated to different metallizations (Au or Co) at the interface. The local Schottky barrier height of the Co patches depends on their lateral extension. This result can be explained by the theory of the potential pinch-off effect in inhomogeneous MS contacts. © 1997 American Institute of Physics.

    Description / Table of Contents: The RAMAN- and TR-spectra of solid, fused, and dissolved (CH3)3SnOH and liquid (CH3)3SnOSn((CH3)3 are reported and the frequencies axe assigned. The spectra of Cl3SnOH and Cl3SnOCH3 · CH3OH are measured to establish the assignement of the SnO-stretching frequency. (CH3)3SnOH forms no H-bridges but associates building Sn-O-Sn-bridges. In aqueous solutions, (CH3)3SnOH is partially dissociated.
    Notes: Die RAMAN- und IR-Spektren des festen und in H2O bzw. CCl4 gelösten (CH3)3SnOH und des flüssigen (CH3)3SnOSn(CH3)3 werden mitgeteilt und die Frequenzen zugeordnet.Zur Sicherung der SnO-Valenzschwingung wurden außerdem die Spektren des Cl3SnOH und Cl3SnOCH3 · CH3OH gemessen. Die Spektren zeigen, daß das |CH3|3SnOH nicht über Wasserstoffbrücken, sondern über Sn-O-Sn-Brücken assoziiert. Der so erreichte Zustand ist offensichtlich sehr stabil, so daß das (CH3)3SnOSn(CH3)3 bereits bei Einwirkung kleinster Mengen Wasser in (CH3)3SnOH übergeht.In den wäßrigen Lösungen des (CH3)3SnOH treten neben undissoziierter Base (CH3)3Sn+-Kationen auf.
