Control and imaging of single-molecule spectral dynamics using a nano-electrode

Abstract
We study the influence of a scanning nano-electrode on fluorescence excitation spectra of single terrylene molecules embedded in thin p-terphenyl films at cryogenic temperatures. We show that applied voltages less than 10 V can result in reversible Stark shifts of up to 100 times and linewidth increase greater than 10 times the natural linewidth. We discuss the potential of our experimental scheme for direct imaging of individual two-level systems (TLS) in the nanometer vicinity of single molecules.
