Conditions for the intensity enhancement of a Bragg reflection are investigated through convergent-beam (CB) reflection electron diffraction experiments. This intensity enhancement is of great interest for reflection electron microscopy of surfaces.

Interference fringes obtained between overlapping diffraction orders in the Kossel-Mollenstedt pattern from a pair of crossed single crystals have been used to demonstrate the degree of coherence across the incident illumination. The experiment also

The work on the observation of moire patterns from overlapping metal films carried out by the authors (1, 2) has already been described in part (3). In this contribution a few of the more important aspects in relation to the application of the techni

The fringe patterns which occur in electron micrographs of overlapping thin crystals were first observed almost simultaneously but independently in 1951 by Mitsubishi, Nagasaki and Uyeda (1), by Hillier (2) and by one of us (J. L. F.) (2) and since t

For the examination of extended specimens such as ribbons of serial sections, thin metal films and some replicas in the electron microscope, it is desirable that the field of view should not be obstructed by grid bars. Suitable supporting substrates

Stereo imaging is not new to electron microscopy. Von Ardenne, who first published transmission pairs nearly forty hears ago, himself refers to a patent application by Ruska in 1934. In the early days of the electron microscope von Ardenne employed a

Oblique illumination, although accompanied by distortion, provides a simple method of obtaining stereoscopic images in a shadow electron microscope. It is not necessary to tilt the specimen.

It has been demonstrated that specimen contamination in convergent-beam diffraction operation can be prevented by maintaining the specimen temperature between -110 °C and -165 °C, without the use of especially high or clean vacuum conditions. At th
