新的ZrB $_2$多晶型:第一性原理计算

New ZrB$_2$ polymorphs: First-principles calculations

Marcin Maździarz, Tomasz Mościcki

摘要:

采用第一性原理密度泛函理论,从结构、力学和热力学性质的角度对两种新的ZrB_2多晶型:(hP_6-P_(63)/mmc空间群,no.194)和(oP_6-Pmmn-空间群,no.59)进行了研究.与已知相(hP 3-P6/mm-空间群,no.191)相反,它们不脆。当用锆掺杂金属硼化物时,关于这些新相的知识可能非常有用。

英文摘要:

Two new hypothetical zirconium diboride (ZrB2) polymorphs: (hP6-P63/mmc space group, no.194) and (oP6-Pmmn-space group, no.59), were thoroughly studied under the first-principles density functional theory calculations from the structural, mechanical and thermodynamic properties point of view. As opposed to the known phase (hP3-P6/mmm-space group, no.191) are not brittle. Knowledge about these new phases can be very useful when doping metal borides with zirconium.
