| 中文摘要 | the ferroelectricity of rhombohedral pbtio3 under uniaxial compression is investigated from first-principles study. upon compression, the ferroelectricity decreases until a critical stress of -29 gpa and then increases with a further increase of the magnitude of the uniaxial compressive stress. we also find that uniaxial compression could enhance piezoelectricity and that the maximum piezoelectric coefficient d(33) occurs at sigma(33)=-49 gpa, which supports the experimentally observed piezoelectric behavior in rhombohedral pb(mg1/3nb2/3o3)-0.32pbtio(3) [q. wan, c. chen, and y. p. shen, j. appl. phys. 98, 024103 (2005)]. our calculated results show that the pb, ti, and o atoms have different contributions to the total polarization with increasing the magnitude of uniaxial compressive stress, and that when -sigma(33)>55 gpa, the ti atoms no longer have contributions to the polarization, which leads to the changes of ferroelectricity and piezoelectricity.
