Photothermal science and techniques
Darryl P Almond,Pravin Patel +1 more
TL;DR: In this article, the photothermal effect is used to generate thermal wave non-destructive evaluation, which is then used for the measurement of semiconducting materials and their properties.
Journal ArticleDOI
The determination of hopping rates and carrier concentrations in ionic conductors by a new analysis of ac conductivity
TL;DR: In this paper, the a.c. conductivity σ(ω) of ionic materials is derived from the new expression ω(0) = A ωpn and the carrier concentration is estimated from σ (0).
Journal ArticleDOI
Transient thermography in the assessment of defects of aircraft composites
TL;DR: In this article, transient thermography was employed in the inspection of defects in various aircraft composite panels, including notches on aluminium alloy panels under carbon or boron composite patching, a simulation of delamination on a BORON composite patch, and fibre breakout on carbon composites.
Journal ArticleDOI
Temperature dependence of the a.c. conductivity of Naβ-alumina
TL;DR: In this paper, the conductivity of β-alumina is of the form σ( ω ) = σ ( ω + Aω n, where n is the value of n. Simple relationships exist between the relative magnitudes of σ and A and their respective activation energies.
Journal ArticleDOI
Impedance and modulus spectroscopy of “real” dispersive conductors
Darryl P Almond,Anthony R. West +1 more
TL;DR: In this paper, power law dispersions in the bulk, intragranular, ac conductivity and permittivity of a non-ideal solid electrolyte are modelled by a frequency-dependent admittance in parallel with the R, C elements of a conventional equivalent circuit.
