采用第一性原理方法系统研究了AlB 2型过渡金属二硼化物(TMB 2; TM = Zr,Sc,Ti,Nb,Y)的高压相变.在受到压力,这些TMB 2化合物经历了普遍的相变从一个AlB 2型到一个新的高压相TP 6结构。原子机制的分析表明,TP 6相是由AlB 2型母相在压力下的原子层折叠而成。稳定性研究表明,TP 6结构的ZrB 2,ScB 2和NbB 2是稳定的,可以在高压下观察到,TP 6结构的TiB 2相可以在环境压力下恢复。
High-pressure phase transitions of AlB2-type transition-metal diborides (TMB2; TM = Zr, Sc, Ti, Nb, and Y) were systematically investigated using first-principles calculations. Upon subjecting to pressure, these TMB2 compounds underwent universal phase transitions from an AlB2-type to a new high-pressure phase tP6 structure. The analysis of the atomistic mechanism suggests that the tP6 phases result from atomic layer folds of the AlB2-type parent phases under pressure. Stability studies indicate that the tP6-structured ZrB2, ScB2, and NbB2 are stable and may be observed under high pressure and the tP6-structured TiB2 phase may be recovered at ambient pressure.
