Ga₂O₃-ZnO系ホモロガス相の構造と高次元空間モデル

抄録

Long-period structures of homologous phases Ga₂O₃（ZnO）_m are closely related to the wurtzite structure of ZnO, and structural evolution is discussed based on the results from structure analyses. A unified structure model for Ga₂O₃（ZnO）_m is established in（3+1）dimensional superspace. Zig-zag functions with large amplitudes are used as modulation functions in the model, which is a common feature in structures constructed by the so-called unit-cell twining. Advantages of the superspace description for homologous phases are explained in relation to the process of identification of materials.
