From: Dimensionality-dependent charge transport in close-packed nanoparticle arrays: from 2D to 3D
Dimensionality-dependent charge transport properties of nanoparticle arrays with different number of monolayers at low temperature.
(a), Temperature-dependent conductance at low voltage bias in a semi-log scale. The logarithm of the zero-voltage conductance of all nanoparticle arrays is linearly proportional to the T−1/2 at low temperature regardless of the layers of the nanoparticle arrays. (b), The coefficient βD in ES-VRH model, which is supposed to depend on the system dimensionality D, as a function of the number of nanoparticle monolayers. Inset: Slopes of the ln(G)-T−1/2 curves shown in (a) plotted as a function of number of nanoparticle monolayers.
