Resumen
Being able to estimate the electron mobility of colloidal quantum dot films is of great importance for determining their suitability to
specific applications and would lead to huge savings in terms of time and resources that may otherwise be wasted trying to build and
optimize a device whose transport characteristics can be predicted to be poor from the outset. This task is however complicated by
the complexity of the system and the large number of parameters that can potentially affect the final result. Here, we derive a simple,
fitting-parameter-free, order-of-magnitude-accurate expression to estimate the dark mobility of such 2D structures and validate it
by applying it to real systems and comparing its predictions with those of other recently proposed approaches and with available
experimental data. The results quantify the superiority of our expression to estimate mobilities in colloidal quantum dot films.
