The discovery1 of high temperature superconductivity in Cu-O based perovskite materials has initiated a large effort in the study of the various physical properties of these materials with a view to obtain a basic understanding of the mechanism of superconductivity in these systems2 In this paper we provide an overview of the positron annihilation studies on high temperature superconductors (HTS). After a brief introduction to the experimental method, the results of positron annihilation studies on high temperature superconductors are presented in three major parts: (1) Studies on the temperature dependence of the annihilation characteristics across Tc, (2) Investigation of the Fermi surface in these materials, and (3) Studies on the structure and defect properties.
