An acoustic deformation potential model appropriate for transport in two dimensions is employed to estimate upper limits on the intrinsic hole mobility of DNTT-C10 [ 2,9-dialkyl-dinaphtho[2,3-b:2,3-f ]thieno[3,2-b]thiophene ], and BTBT-C12 [ 2,7-dialkyl[1]benzo-thieno[3,2-b][1]benzothiophene ]. Comparison is made to calculations for a thin-film pentacene structure. First-principles calculations are employed to determine the values of effective masses, deformation potentials and elastic constants entering the model. The effective masses calculated for the holes in DNTT-C10 and BTBT-C12 are significantly less than those obtained for the thin-film pentacene, and this difference is expected to give rise to better hole transport in these materials.
