Abstract Inspired by the newly observed and $X_1(2900)$?> states at LHCb, $K^*\bar{D}^*$?> $K\bar{D}_1$?> interactions are studied in quasipotential Bethe-Salpeter equation approach combined with one-boson-exchange model. The bound virtual from searched for as poles complex energy plane of scattering amplitude. A state $I(J^P)=0(0^+)$?> a $0(1^-)$?> produced interaction ...
This manuscript reports the temperature dependence of ferroelectric switching in Al0.84Sc0.16N, Al0.93B0.07N, and AlN thin films. Polarization reversal is demonstrated all compositions strongly dependent. Between room 300 °C, coercive field drops by almost 50% samples, while there was very small remanent polarization value. Over this same range, relative permittivity increased between 5% 10%. c...
Alternating current poling (ACP) was performed on Gen III relaxor-PT Mn-doped Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (Mn: PIN-PMN-PT) single crystals with the direction of [001]. Experimental results proved that ACP could bring property enhancement to both k31 and k33 mode crystals. Compared those from traditional direct (DCP), optimized conditions (20 kV/cm, 0.1 Hz, 20 cycles) enhanced diele...
