where ε is the relative dielectric constant that equals to 5 for (BA)2(MA)2Pb3I10, ε0 is the vacuum permittivity, μ is the carrier mobility and L is the distance between the electrodes. The hole mobility alon
Annealing temperature is varied between 560 and 700 °C in order to optimize the detectivity figure of merit Fd=p/[c(εrε0 tan δ)1/2] (where p is pyroelectric coefficient, c is volume specific heat, εr is the relative dielectric constant, ε0 is dielectric constant of free ...
the trap-filled limit voltage (VTFL) [32], which allows to estimate the trap density (ntrap) through:(1)ntrap=2εε0VTFLeL2where e is the elementary charge, L is the thickness of perovskite layer, ε is the relative dielectric constant of perovskite, and ε0 is the vacuum ...
Indeed, the above observations suggest that the origin of this dielectric peak in BNT materials should not be related to structural phase transition. Notice also in Fig.1a that when the BNT sample was subjected to reduction in high-vacuum at 1123 K for 6 h, a decrease in the dielectric per...
where R is the effective radius of the probe tip, D is the separation distance between the tip and the surface, ε0 is the vacuum permittivity, ε is relative dielectric constant of the medium (aqueous medium in these experiments), and κ is the inverse of the Debye length in the electro...
Barium titanate so far used as a dielectric substance has a sintering temperature as high as 1,300°-1,400° C., and has the relative dielectric constant of 1,500 at the room temperature and the relative dielectric constant of 6,000 at the curie point (120° C.). ...
The introduction of (Mn1/3Nb2/3)4+ effectively suppressed the formation of the MgTi2O5 phase. The variation trend of the dielectric constant (εr) was the same as relative density. The quality factor (Qf) value was enhanced by the stable microstructure, which was caused via the lattice ...
A strip of adhesive copper tape, connecting with the sample and the sample mount, was placed in contact with each piece of aerogel to avoid charging during imaging. The samples were also sputter-coated with platinum, and then imaged. Compression tests were carried out on the universal testing ...
In order to get the hydrogen gas into solution a Teflon-bonded platinum black catalyst is used, similar to that used in fuel cells. This platinum electrode has the added advantage that it can recombine oxygen with hydrogen extremely fast. Since the only bad chemical reaction during over charge...
Semi-metals present unique transport properties due to their distinctive band structures and topological properties, leading to an emergence of semi-metal-based electronic applications. Specifically, these properties include intrinsic low density of stat
