摘要
A stable and stoichiometric Cu2C2 phase in nanoparticle form has been synthesized using activated reactive evaporation technique. X-ray diffraction, transmission electron microscopy, and x-ray photoelectron spectroscopy studies reveal the formation of a stoichiometric Cu2C2 nanophase having a tetragonal structure. Cu2C2 samples have a high absorption coefficient with a size-dependent optical absorption edge and n-type semiconducting nature. Due to its structural stability, chemical compatibility with other low-cost semiconductor materials, and suitable electrical and optical properties, the Cu2C2 phase has the potential of emerging as a semiconductor material.
