The Discovery of Plasmon Resonance in Germanide Nanowires Grown on Cu Foil

Abstract

Free-standing and single-crystalline Cu 3 Ge nanowires (NWs) were synthesized by a vapor-phase deposition method on the Cu foil. The NWs are grown along the [010] direction via a vapor-solid mechanism. The localized surface plasmon resonance of individual NWs on a Si substrate is investigated using the dark-field scattering spectroscopy. The resonance peak wavelength for NWs with different diameters is observed, which ranges from 500 to 550 nm. This study proves the existence and provides an insight for understanding the LSPR property of free-standing Cu 3 Ge NWs.

“…All of the Si substrates were cleaned by a standard Radio Company of America process and dilute hydrofluoric acid dipping prior to the growth process [17][18][19]. Iron silicide nanowires were synthesized in a horizontal furnace by a chemical vapor transport method [20,21]. Before temperature ramping, the quartz tube was evacuated below 1 × 10 −2 Torr.…”
