STM-induced light emission from thin films of perylene derivatives on the HOPG and Au substrates

<p>Abstract</p> <p>We have investigated the emission properties of <it>N,N</it>'-diheptyl-3,4,9,10-perylenetetracarboxylic diimide thin films by the tunneling-electron-induced light emission technique. A fluorescence peak with vibronic progressions with large Stoke...
