Growth of nanometric CuGaxOy structures on copper substrates

This paper presents an alternative method based on the metal-organic chemical vapour deposition technique to obtain new nanowire structures. Here, the metal-organic precursor acts as a catalyst and interacts with a metallic substrate to produce 3D structures such as nanowires. In the present case, trimethyl gallium interacts with a copper metallic substrate to build a single-crystalline CuGaxOy wire structure. Electronic microscopy techniques on image or diffraction modes have provided the structural and chemical characterization of the obtained nanowires.
