Ab Initio Linear Response Study of SrTiO3
Chris LaSota, Cheng-Zhang Wang, Rici Yu +1
The lattice instabilities of perovskite structure oxides are responsible for many of their interesting properties, such as temperature-dependent ferroelectric phase transitions. Fi…

Polarization Dependence of Born Effective Charge and Dielectric Constant in KNbO
Cheng-Zhang Wang, Rici Yu, Henry Krakauer
The Born effective charge Z^{*} and dielectric tensor ε_{\infty} of KNbO_3 are found to be very sensitive to the atomic geometry, changing by as much as 27% between the paraelectri…

Pressure Dependence of Born Effective Charges, Dielectric Constant and Lattice Dynamics in SiC
Cheng-Zhang Wang, Rici Yu, Henry Krakauer
The pressure dependence of the Born effective charge, dielectric constant and zone-center LO and TO phonons have been determined for -SiC by a linear response method based on t…
