摘要
Strontium-zinc-oxide(SrZnO)filmsformingthesemiconductorlayersofthin-filmtransistors(TFTs)aredepositedbyusingion-assistedelectronbeamevaporation.Usingstrontium-oxide-dopedsemiconductors,theoff-statecurrentcanbedramaticallyreducedbythreeordersofmagnitude.Thisdramaticimprovementisattributedtotheincorporationofstrontium,whichsuppressescarriergeneration,therebyimprovingtheTFT.Additionally,thepresenceofstrontiuminhibitstheformationofzincoxide(ZnO)withthehexagonalwurtzitephaseandpermitstheformationofanunusualphaseofZnO,thussignificantlychangingthesurfacemorphologyofZnOandeffectivelyreducingthetrapdensityofthechannel.
