Discovery of a new weberite-type antiferroelectric: La3NbO7
Louis Alaerts, Jesse Schimpf, Xinyan Li +7
Antiferroelectrics are antipolar materials which possess an electric field-induced phase transition to a polar, ferroelectric phase and offer significant potential for sensing/actu…
Direct determination of antiferroelectric-to-ferroelectric phase transition pathways in PbZrO with Operando Electron Microscopy
Menglin Zhu, Michael Xu, Louis Alaerts +5
Under a sufficiently high applied electric field, a non-polar antiferroelectric material, such as \ce{PbZrO3}, can undergo a rapid transformation to a polar ferroelectric phase. Wh…
First principles computations of the Stark shift of a defect-bound exciton: the case of the T center in silicon
Louis Alaerts, Yihuang Xiong, Sinéad M. Griffin +1
The T center in silicon has recently drawn a lot of attention for its potential in quantum information science. The sensitivity of the zero-phonon line (ZPL) to electrical field wa…
A first principles study of the Stark shift effect on the zero-phonon line of the NV center in diamond
Louis Alaerts, Yihuang Xiong, Sinéad Griffin +1
Point defects in semiconductors are attractive candidates for quantum information science applications owing to their ability to act as spin-photon interface or single-photon emitt…
