聚噻吩瞬态输运性质的研究 研究聚噻吩（polythiophene）的瞬态输运性质 Abstract: Polythiophenesareaclassofconjugatedpolymerswith excellentelectricalandopticalproperties.Theyhavebeen extensivelyusedinvariouselectronicandoptoelectronicdevices, suchassolarcells,transistors,andlight-emittingdiodes. Understandingthetransienttransportpropertiesof polythiophenesiscrucialforoptimizingtheirdeviceperformance. Inthispaper,wereviewtherecentprogressinstudyingthe transienttransportpropertiesofpolythiophenes,includingthe chargecarrierdynamics,mobility,andrecombination.Wediscuss theexperimentalmethodsthathavebeenemployedto investigatetheseproperties,suchastime-resolvedspectroscopy andtransientphotoconductivitymeasurements.Furthermore,we presentthetheoreticalmodelsandsimulationsthathavebeen developedtoexplaintheobservedtransienttransport phenomena.Finally,wediscusstheimplicationsofthesefindings forthedevelopmentofhigh-performancepolythiophene-based electronicandoptoelectronicdevices.
