    Nanometer scale structure fabrication with the scanning tunneling microscope (1987)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: Nanometer scale structures have been produced on atomically flat surfaces of metallic glasses using the scanning tunneling microscope in the tunneling mode with enhanced local current densities and strong electric fields. Depending on the current and the electric field enhanced diffusion, local crystallization of the glassy state or Taylor cone formation of the locally molten surface can occur. These structures provide a potential means of studying the behavior of matter at nanometer dimensions.

    Hydrogenated amorphous silicon studied by scanning tunneling microscopy (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have used scanning tunneling microscopy under ultrahigh vacuum conditions in order to study the local electronic properties, as well as the topographical and chemical structure of hydrogenated amorphous silicon. Local characteristics were measured and images of the topography, as well as simultaneously recorded images of the local tunneling barrier height, were obtained with subnanometer resolution. The experimental results demonstrate that chemical inhomogeneities on a subnanometer scale, which may be caused by the presence of hydrogen in these samples, can be detected in the local tunneling barrier height images.

    Observation of magnetic forces by the atomic force microscope (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 62 (1987), S. 4293-4295

    Notes: We present a new way to observe the surface domain distribution of a magnetic sample at a submicrometer scale. This magnetic microscopy is based on the idea of measuring magnetic forces with the recently developed atomic force microscope (AFM). We study the magnetic forces involved in the interaction between a single-domain microtip and the sample surface magnetic domains. The influence of the experimental conditions on the performance of the AFM as a magnetic profiling device is also discussed. Preliminary experimental results are reported.

    Magnetic imaging by atomic force microscope (invited) (abstract) (1988)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 63 (1988), S. 2947-2947

    Notes: A new method of imaging the surface of magnetic samples on a submicron scale is described and the observation of magnetic domain walls is presented. Measurements in air on a Co-Ni recording media, polycrystalline Ni foil and rapidly quenched alloys are shown. This magnetic microscope is based on the idea of measuring magnetic forces with the recently developed atomic force microscope (AFM). Forces acting on a tip are recorded by the measurement of the deflection of a lever to which this tip is attached. In order to measure ultra small forces (less than nN), the spring constant of the lever has to be small and the deflection of the lever has to be measured with great sensitivity, i.e., by using interferometry or scanning tunneling microscopy (STM). The lever is made from ferromagnetic Ni foil with an integrated, electrochemically etched tip. Different measuring modes of the AFM are described. The images obtained by the AFM using a para- or ferromagnetic tip and by the STM are compared. Furthermore, the results obtained by the magnetic AFM on Co-Ni recording media are compared with previous studies by scanning electron microscopy with polarization analysis (SEMPA).

    Notes: Zusammenfassung Es wurden eine große Anzahl von Spirituosen verschiedenster Art und Herkunft auf ihren Gehalt an Aerolein untersucht und bei einer großen Anzahl Aerolein gefunden. Von den Ausnahmen sind die Edelbranntweine des Handels erwähnenswert, die höchstens Spuren von Aerolein enthielten. Im Anschluß daran wurden Haltbarkeitsversuche gemacht. Ferner wurde der Einfluß verschiedener Stoffe auf Aerolein untersucht und ein technisches Verfahren angegeben, mit dem das Aerolein des Branntweins völlig oder fast völlig, das des Sprites völlig abgetrennt werden konnte.
