Abstract

Free-standing and single-crystalline Cu₃Ge 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 Cu₃Ge NWs.
