Optoelectronics and Advanced Materials, Rapid Communications, 10(11-12), 825-830.1842-65732065-3824http://hdl.handle.net/11452/33266We fabricated the Au/Meh-PPV:PCBM/n-type GaAs Schottky barrier diodes (SBDs). Then we investigated Current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the diode at room temperature. MEH-PPV:PCBM (in a mass ratio 1:4) used as interfacial layer between metal and semiconductor layers. Here, MEH-PPV is poly [2-methoxy-5-(ethylhexyloxy)1,4-phenylenevinylene] and PCBM is [6,6]-phenyl-61C-butric acid methyl ester). SBD parameters such as ideality factor, barrier height and series resistance were obtained from I-V and C-V measurements. Also, Cheung functions and Norde Method were used to evaluate the I-V characteristics and to determine the characteristic parameters of the Schottky diode. The diode parameters such as ideality factor, barrier heights and series resistance were found as 4.39-4.54 and 0.57-0.63 eV and 51-53 Omega respectively. Also the interface states energy distribution of the diode was determined and found as 1.09 x 10(12) ev(-1)cm(-2)at (Ec-0.352) eV to 2.94 x 10(11) eV(-1)crn(-2) at (Ec-0.436) eV.eninfo:eu-repo/semantics/closedAccessMaterials scienceOpticsSchottky barrier diodeSeries resistanceIdeality factorConducting polymersState density distributionsElectronic parametersV characteristicsCurrent-voltageC-VInterface statesI-VMechanismPPVCapacitanceElectric resistanceGallium arsenideGold compoundsIII-V semiconductorsInterface statesSemiconducting galliumSemiconductor diodesCapacitance-voltage characteristicsEnergy distributionsIdeality factorsInterfacial layerIV characteristicsSchottky barrier diodes (SBDs)Semiconductor layersSeries resistancesSchottky barrier diodesArticle0003917779000082-s2.0-850086981608258301011-1227221456Materials science, multidisciplinaryOpticsSchottky Diodes; Thermionic Emission; Electrical Properties
