It is found that the depolarization rates at the low temperatures below 50 K indicate that the H-0.5 field-dependent characteristics of the charge transport is dominated by mobility along the polymer chain (intrachain diffusion). With an increase in temperature, the charge carriers move perpendicular to the polymer chain (interchain diffusion), as characterized by the field dependence of depolarization rates of C-H0.5 curve. The initial change in the carrier mobility appeared at around 50 K to 75 K.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Carrier diffusions,Carrier hopping mechanism,Dependent characteristics,Field dependence,Longitudinal fields,Muon spin relaxation,RR-poly(3-butylthiophene-2,5-diyl),Temperature dependent[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]charge carrier diffusion,LF-μSR,RR-poly(3-butylthiophene-2,5-diyl)[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We thank Dr. Ishii, Dr. Oishi and Dr. Suzuki for experimental assistance.
