摘要 TheMOCVDgrowthofmodifiedAlAs/GaAsdoublebarrierresonanttunnelingdiodes(DBRTD)withanA1GaAschairwasreported.Theresonancestothefirstexcitedstateswereobtained.Thepeak-to-valleycur-rentratio(PVCR)is1.3at77K,roomtemperaturepeakcurrentdensityis8kA/cm~2.Theresonancevoltagesareinagreementwiththetheoreticalapproachbytransfer-matrixmethod.Influenceofinterruptedgrowthtimeatthehetero-interfaceandincorporationoftheAlGaAschairtothedeviceperformanceswerestudiedandthemechanismwasdiscussed.TheattempttoaddanAlGaAschairtotheDBRTDbyMOCVDresultedinimprovementinthePVCRandpeakcurrentdensity.
