We experimentally observed an enhancement of the third harmonic (TH) signal at Au/Al2O3/Au interfaces. The TH signal behavior with surface coverage qualitatively resembles the quantum tunneling predictions.

We experimentally observed an enhancement of the third harmonic (TH) signal at Au/Al2O3/Au interfaces. The TH signal behavior with surface coverage qualitatively resembles the quantum tunneling predictions.File in questo prodotto:
