Abstract
We report on muon-spin-relaxation (lSR) experiment of organic semiconductor spirolinkedcompound 20,70-bis(N,N-diphenylamino)-2-(5-(4-tert-butylphenyl)-1,3,4-oxadiazol-2-yl)-9,9-spirobifluorene (Spiro-DPO) measured at temperatures between 8 and300 K and at longitudinal fields up to 395 mT in order to study charge transport propertiesin organic semiconductor. The lSR time spectra were analyzed by using Risch and Kehr(RK) function and it indicates a transition from one-dimensional hopping transport ofcharge carriers at low temperatures to two- or three-dimensional hopping transport athigh temperatures (>75 K).
