Synthesis of β-Ga2O3/diamond-like carbon core-shell heterostructure nanowires |
| 초록 |
We report β-Ga2O3/diamond-like carbon (DLC) core-shell heterostructure nanowires fabricated by vapor-liquid-solid method and radio frequency plasma enhanced chemical vapor deposition (PECVD). As-synthesized β-Ga2O3 nanowires have widths of 30-150nm and outer shell DLC thickness was in a range of 20-30nm. The products were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersed spectrometry (EDS). In addition, outer DLC layer was confirmed by Raman spectroscopy, which shows typical two Raman bands at 1550 cm-1 (G peak) and 1330 cm-1 (D peak) corresponding to disordered graphite peak. This novel type of core-shell heterostructure nanowire can provide potential applications in optoelectronic nano-devices, nano-sensors, and magnetic nano-devices. |
