Abstract
Previously in observations made with small MgO crystals it was shown that when an electron beam of small diameter is made to run parallel to a flat face of the crystal, it may be deflected towards thp crystal by the potential field extending from the crystal into the vacuum. The deflection of the electron beam could be seen clearly in observations of microdiffraction patterns made with the optical detector system added to the HB5 dedicated STEM instrument. The direction and magnitude of the deflection and the form of the displaced spot were shown to be consistent with reasonable models from the field distribution. Because little appears to be known concerning the form of the field for insulators such as MgO, we have chosen to use gold crystals for attempts to determine quantitatively the form of the potential field. Various models have been used for the potential field.
