Stallinga, PeterGomes, Henrique L.2015-06-262015-06-2620061566-1199AUT: PJO01566; HGO00803;http://hdl.handle.net/10400.1/6600Based on the model of thin-film transistors in which the active layer is treated as two-dimensional, the effects of traps are studied. It is shown that when abundant discrete trap states are present, the field-effect mobility becomes temperature dependent. In case the traps are distributed exponentially in energy, a Meyer-Neldel rule for the temperature dependence of mobility and current results. When also the mobile states are distributed in energy, in the so-called band-tail states, the mobility is no longer thermally activated. (c) 2006 Elsevier B.V.
