NEGATIVE ION IMAGING IN FIELD ION MICROSCOPY

The most striking pheno- mena observed in TCNE anion images are the appearance of ring struc- tures and their discontinuous change with increasing field strength applied to

If it is possible to apply a high electric field, which is enough to cause field ionization of image gases, even to the tip with a larger radius of curva- ture, a further extension

Abstract- Flickering and hopping of spots in the argonimage of an a-SkH layer on tungsten was investigated by studying the kinetics of the responsible adsorvtion and desorvtion

Mn by transmission electron microscopy (TEM), electron diffraction in TEM, and x-ray diffraction indicated a structure characterized by long-range icosohedral symmetry and

Electron micrographs and electron diffraction patterns were obtained from tungsten specimens after controlled amounts of field evaporation.. From a knowledge of the changes

The maximum value of the ionization distribution D(z) will be denoted by D (z) and the corresponding z-coordinate by z For not too high values of the tip fTeld strength,
