Abstract

We address the role of apical oxygen that plays the bridges linking charge reservoir and CuO₂ conducting layers for high T_c superconductors (HTS). The presentation will introduce our recent work on high pressure synthesis of novel superconductors in the A-Cu-O simple system by tuning apical oxygen content and arrangement (A represents alkaline earth element). The topic will focus on 214 type compounds highlighting apical oxygen as a novel doping mechanism in oxychloride HTS, or dopant at a partially occupied apex, especially the unusual enhancement of T_c up to 95 K in a monolayered HTS by improving ordering state.
