Flame ionization detectors and devices which measure this quantity are the most common detector types used in gas chromatography.
Nika et al. calculated this quantity's value for graphene in terms of the Gruneisen parameters for LA and TA modes using the Klemens approximation. This quantity equals pi squared over 3 times the ratio of Boltzmann's constant to the fundamental charge squared times temperature times electric conductivity according to the Wiedeman-Franz law. This quantity would be infinite in a perfectly harmonic crystal. At high temperatures, this quantity falls off as one over temperature, since umklapp processes become dominant, decreasing the phonon mean free path. Flame ionization detectors and devices which measure this quantity are the most common detector types used in gas chromatography. This quantity is found in the denominator of the Nusselt number. For 10 points, name this quantity, which multiplies minus the temperature gradient to give the heat flux in Fourier's law.
