Under the light microscope the lengths of the sutures range from approximately 10– μm. The sutured grain boundaries are statistically self-similar over one to two orders of magnitude.

They represent fractals. Their mathematical counterpart are Koch curves which Cited by: dices (2,1) for the vertical face of the grain boundary. We set up the grain boundary by initializing two rect-angular grains with the given rotations that define the grain boundary geometry we wish to measure.

In the current paper a new method is presented that determines the five macroscopic parameters of a grain boundary (GB) from electron diffraction patterns and bright field (BF) images in a transmission electron microscope. Usefulness of the method is demonstrated on a set of GBs measured in laser crystallized Si thin films.

Grain Boundaries -Their Microstructure and Chemistry discusses the interrelationship between microstructure and chemistry of the grain boundary, with particular emphasis on the influence of the environment (air, liquid and liquid metal) and composition (bulk and impurity). An experimental method to obtain the grain boundary geometry using the transmission electron microscope is presented.

The method allows Σ determination including grain boundary plane orientation.
