摘要：

The structure model for HgTlBa2CuOx, was proposed from high-resolution electron microscopy using residual indices. Averaged digital high-resolution image of the HgTlBa2CuOx, showed the existence of separated Hg layers and oxygen vacancies in the double (Hg,Tl) layers. Image calculations based on the proposed structure model of HgTlBa2CuO5 agreed well with the observation, and showed low residual values. The present result indicates the stability of the (Hg, Tl) double layer structure would be due to the formation of oxygen vacancies in the Hg layers.
