    Notes: YBa2Cu3O7 films can be grown on different substrates by the off-axis ac magnetron sputtering method. Films in the ab orientation tend to grow at a lower substrate temperature than c-axis films. However, as the temperature is lowered, all the substrates we have tested, except for SrTiO3, form amorphous phases that degrade the quality of the films being made. In this manuscript it is shown that if a thin layer of c-axis film is deposited on the substrate first, then it effectively reduces the formation of the amorphous phases and improves the film quality significantly.

    A piezoelectric-driven micropositioner with magnetic locking mechanism (1991)

    Notes: A micropositioner has been constructed with a piezoelectric tube and walking pads locked by magnets. These magnets were arranged in a special geometry to prevent slipping and trapping. The magnetic force created was large enough to operate the walker in any orientation. Tolerance of surface roughness was much higher than other similar types of micropositioners.
