ABSTRACT A systematic study of orthorhombic phase formation at ambient conditions beyond a critical concentration of dopant Tantalum (Ta) in HfO is reported. The effect on the path of structural evolution due to Ta doping in HfO was also investigated. Studies on Ta-doped HfO samples and their path of structural evolution under compression have significant implications for materials undergoing β-decay. The effect of continual doping due to β-decay from geophysical point of view is discussed.

HfO2 中的钽掺杂：环境条件下正交相的形成和压力诱导结构演化路径的变化

摘要报道了在 HfO 中超过掺杂剂钽 (Ta) 临界浓度的环境条件下正交相形成的系统研究。还研究了由于在 HfO 中掺杂 Ta 对结构演化路径的影响。对掺 Ta 的 HfO 样品及其在压缩下的结构演化路径的研究对经历 β-衰变的材料具有重要意义。从地球物理的角度讨论了由于 β-衰变引起的连续掺杂的影响。
