摘要

There are many kinds of metastable structures found in the phase diagrams of most materials.Although some structures have been found under extreme temperature and pressure,there are still structures not yet predicted in the existing phase diagram.Many kinds of silver iodide structures have been found under high pressure or high temperature including the α phase,rock-salt phase and potassium hydroxide-like structures [1].However,it remains a big challenge to experimentally detect unpredicted structures and to stabilize these metastable structures of silver iodides.
