Hof, A. Oosthoek, J.L.M. Blom, P.W.M. Publication year 2011 Abstract The charge transport in blue light-emitting polyspirobifluorene is investigated by both steady-state current-voltage measurements and transient electroluminescence. Both measurement techniques yield consistent results and show that the hole transport is space-charge limited. The electron current is found to be governed by a high intrinsic mobility in combination with electron traps. Numerical simulations on light-emitting diodes reveal a shift in the recombination zone from the cathode to the anode with increasing bias. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
