Pressure-induced metal-insulator transition in oxygen-deficient LiNbO-type ferroelectrics
Chengliang Xia, Yue Chen, Hanghui Chen
Hydrostatic pressure and oxygen vacancies usually have deleterious effects on ferroelectric materials because both tend to reduce their polarization. In this work we use first-prin…

Coexistence of polar displacements and conduction in doped ferroelectrics: an ab initio comparative study
Chengliang Xia, Yue Chen, Hanghui Chen
Polar metals are rare because free carriers in metals screen electrostatic potential and eliminate internal dipoles. Degenerate doped ferroelectrics may create an approximate polar…
