Length-scale dependent average structures, piezoelectricity enhancement and depolarization mechanisms in a non-MPB high-performance piezoelectric alloy system PbTiO3-Bi(Zr1/2Ni1/2)O3
Rishikesh Pandey, Dipak Kumar Khatua, Shekhar Tyagi +4
There is a general perception that large piezoelectric response in ferroelectric alloys requires tuning the system towards a morphotropic phase boundary (MPB), i.e., a composition…
Tuning photoluminescence response by electric field in the lead-free piezoelectric Na1/2Bi1/2TiO3-BaTiO3
Deepak Kumar Khatua, Abhijeet Kalaskar, Rajeev Ranjan
We show that an electrically soft ferroelectric host can be used to tune the photoluminescence (PL) response of rare-earth emitter ions by external electric field. The proof of thi…
Electric field induced irreversible transformation to the R3c phase and its influence on the giant piezo-strain behaviour of lead-free system- Na0.5Bi0.5TiO3-BaTiO3-K0.5Na0.5NbO3
Dipak Kumar Khatua, Anatoliy Senyshyn, Rajeev Ranjan
A systematic study of the structural, dielectric and piezoelectric behavior of NBT-BT-KNN.
Monoclinic (Mc) phase and electric field induced phase transformation in BaTiO3
Ajay Kumar Kalyani, Dipak Khatua, B. Loukya +4
For decades it has been a well-known fact that among the few ferroelectric compounds in the perovskite family namely BaTiO3, KNbO3, PbTiO3 Na1/2Bi1/2TiO3 the dielectric and piezoel…
