| 英文摘要 | Tetragonal pbtio(3) under uniaxial stress along the c-axis is investigated from first-principles. the structural parameters, polarization, and squares of the lowest optical phonon frequencies for e(1to) and a(1)(1to) modes at gamma show abrupt changes near a stress sigma(c) of 1.04 gpa, which is related to the dramatic change of elastic constant c(33) resulting from the uniaxial stress applied along the c-axis. we also find that the uniaxial compressive stress could enhance the piezoelectric stress coefficients, whereas the uniaxial tensile stress could enhance the piezoelectric strain coefficients. it is also found that when the magnitude of uniaxial compressive stress sigma(33) is greater than 12 gpa, pbtio3 is transformed to the paraelectric tetragonal phase. |
