摘要 MultilayergalliumandaluminumdopedZnO(GZO/AZO)filmswerefabricatedbyalternativedepositionofGa-dopedzincoxide(GZO)andAl-dopedzincoxide(AZO)thinfilmbyusingpulsedlaserdeposition(PLD)process.TheelectricalandopticalpropertiesoftheseGZO/AZOthinfilmswereinvestigatedandcomparedwiththoseofGZOandAZOthinfilms.TheGZO/AZO(1:1)thinfilmdepositedat400°Cshowstheelectricalresistivityof4.18×10-4Ω·cm,anelectronconcentrationof7.5×1020/cm3,andcarriermobilityof25.4cm2/(V·s).TheopticaltransmittancesofGZO/AZOthinfilmsareover85%.TheopticalbandgapenergyofGZO/AZOthinfilmslinearlydecreaseswithincreasingtheAlratio.
