Application of positron annihilation as a nondestructive method of checking the quality of materials

Positronics and nanotechnologies: Possibilities of studying nano-objects in technically important materials and nanomaterials

“…The second group use fast positrons that penetrate investigated materials to greater depths > 50 mm and can give information on the type, concentration, and distribution of defects in a solid. All these methods are widely used by the materials science community especially to probe nuclear and electronic materials (see, for example, references [7][8][9][10][11][12][13][14][15][16][17]). …”

“…The following points can be drawn from a study of the literature on the application of PAS to nanocrystals of metals and alloys [2][3][4][5][6][7][8], semiconductors [9][10][11][12][13][14][15][16], and porous silicon and polymers [5,17,29].…”
