| บทคัดย่อ/คำอธิบาย | : | Ballisticelectron emission spectroscopy (BEES) was used to determine the electron barrier height at the interface of Au and an oxidizedGaAs film. Two thresholds were observed in the spectra. In a two-step procedure, we identified the first threshold at ∼1.4 eV, which we show arose from electron-hole pairs excited by photons emitted during scanning tunneling microscopy(STM), and the second threshold at ∼3.55 eV, which is attributed to the Au/oxidized-GaAs barrier. Our results demonstrate that the two-threshold behavior observed in BEES studies on metal/oxide samples is amenable to a physical model comprising of STMphotocurrent and a metal/oxide interface barrier. |
