Description

The effects of crushing the crystals were investigated by conductivity and by positron annihilation lifetime measurements. As in untreated Tl4Cl6, the conductivity variation with temperature shows a break at about 450 K. The positron lifetime variation with increasing temperature shows some contribution of extrinsic defects. On further heating or cooling cycles, the lifetime changes are controlled by the production of intrinsic cation vacancies. (author)
