Nettet14. mar. 2024 · In this case, which will especially occur for thicknesses and injection barriers typical of single-carrier devices used to probe organic semiconductors, a meaningful analysis using the Mott-Gurney law will become unachievable, because a square-law fit can no longer be achieved, resulting in the mobility being substantially … NettetThe Mott-Gurney equation (Child’s law) has been frequently applied to measure the mobility of carrier transport layers. One of the main assumption in the Mott-Gurney theory is ignoring the diﬀusive currents. It was not obvious, however, whether the diﬀusive currents can be ignored for thin carrier transport layers.
