InFig. 5bwe also compare the energy density of BNFO with other previously reported top energy-storage materials—that is, lead-based5,6,33,34,35and lead-free10,11perovskites—for different experimentally appliedEmax. We find that, taking BNFO withx=1 andE-field along [001] as a reference...
The domain morphology and crystal structure of (l-x)(Bi_(1/2)Na_(1/2))TiO_3-xBaTiO_3 lead-free piezoelectric ceramics were systematically studied with transmission electron microscopy for compositions x=0.04 through 0.11. It was found that the ceramics with-compositions x<0.06 display a R3c...
The ferroelectricity in the hybrid perovskite CH3NH3PbI3 is under debate because it results from the polar molecular cation CH3NH3+ while the molecular orientation was reported to be random. Here we predict that a Pb-free hybrid perovskite N(CH3)4SnI3 wi
In the recent years, lead-free solder material have been increasingly applied to the green semiconductor products for RoHS compliance. For Flip Chip Plastic Ball Grid Array (FCPBGA), recent industry trend is changing from ENIG pad finishing to Solder-on-pad (SOP) pad finishing using Sn3.0Ag0.5...
