Phys. Rev. B 24, 5650–5663 (1981)Light emission from tunnel junctions on gratingsReceived 24 April 1981; published in the issue dated 15 November 1981 We present measurements of light emission from Al-Al2O3-Ag tunnel junctions on holographically produced, sinusoidal profile gratings. Sharp angle tunable emission peaks result from coupling out of the Ag-vacuum fast surface-plasmon polariton by the grating structure. The dependences of the emission intensities on angle, frequency, bias voltage and current, and grating amplitudes agree well with a recent theory by Laks and Mills [ Phys. Rev. B 22 5723 (1980)]. The absolute intensities and dependence of intensities on Ag-film thickness do not agree as well. We propose a possible explanation for this discrepancy.
