Dimensionality-dependent Coulomb charging energy in nanoparticle arrays at medium temperature.
(a), The Coulomb charging energy of nanoparticle arrays with different number of monolayers. Inset: The zero-voltage conductance of nanoparticle arrays with different thickness as a function of inverse temperature at medium temperature ranging from 75 K to 130 K. (b), The normalized measured and calculated Coulomb charging energy of nanoparticle arrays as a function of number of nanoparticle monolayers. The normalized calculated Coulomb charging energy are relay on the assumption of the self-capacitance and mutual capacitance of nanoparticles. Inset: Schematics of the nearest-neighbor-number of an individual nanoparticle in monolayer arrangement (left), bilayer arrangement (middle) and trilayer arrangement (right).
