Evaluation of Charge Transport in a Percolating Network of Disordered Organic Thin Films

摘要

Understanding effective carrier transport on percolating network is important for semiconductor device optimization. Structural as well as dynamical properties of percolation network such as hopping or tunneling length, conducting path, correlation length, system conductivity and resistivity are significant parameters that determine charge carriers mobility across the thin film module. In this work, we describe an alternative method to quantify the geometry of connectivity and the statistical variability of conductivity, and also show that the percolating transport exponent are highly correlated with fractal dimension of the active layer topology.
