Fabrication and characterization of GeO2-PbO optical waveguides
(2009-12-01)
This work presents studies of GeO2-PbO thin films deposited by RF Sputtering for fabrication of rib-waveguide. GeO2-PbO vitreous targets were prepared melting the reagents in alumina crucible. Thin films were deposited at ...

Effect of nearest neighbor Pb-O divacancy pairs on the ferroelectric-relaxor transition in Pb(Sc1/2Nb1/2)O3
(American Physical Society, 2008-12)
Molecular dynamics simulations were performed on a frst-principles-based effective Hamiltonian for Pb(Sc1/2Nb1/2)O3 (PSN) with nearest neighbor Pb-O divacancy pairs. Simulations were performed for PSN with ideal chemical ...
