Abstract
The general techniques necessary to produce a highβquality crossβsectioned ceramic specimen for transmission electron microscope observation are outlined. A particularly important point is that the width of the glued region between faces of the ceramic specimen must be < 0.2 ΞΌm to prevent loss of the nearβsurface region during ion milling. A recently developed vise for gluing ceramic crossβsection specimens is described, and some examples of the effect of glue thickness on specimen quality are shown.

A novel cross-sectional sample preparation technique for quantum wire (QWR) structures is described. By coating a thin layer of Au with a designed pattern on the sample as a marker to indicate the position of the wire pattern, the location of the thinned area can be controlled precisely. An example
## INTRODUCTION. The high temperature oxidation of alumina-and chromia-forming metals and alloys has been studied for many years. Although it is fairly easy to produce TEM cross-sections of the adherent scales formed on alloys containing reactive elements it has proved more difficult to cross-sect
The rocking-angle ion-milling technique has been employed to produce optimum Pt/Ti/SiO,/Si, WITiN/Si021Si, and (Pb,La)TiO,/Pt/MgO samples for cross-sectional transmission electron microscopy (TEM). Because of the different ion-milling rates between film layers and substrate materials, no satisfactor
## Abstract A method is described for the preparation of crossβsectional samples of thin films for transmission electron microscopy. The technique produces larger amounts of thin region as compared with ion milling and eliminates the problems associated with ion beam damage. The requirement is that
