| Abstract | 介绍了巴基葱的一种制备方法 ,用扫描探针显微镜 (SPM )观测了巴基葱的微观形态 ,发现巴基葱存在两种形状的聚合体 :“熊掌”形和“葫芦”形 ,它们的轴向呈现较严格的一致 ,存在成串排列的巴基葱聚合体 ,探讨了这些现象产生的原因 ,并在大气室温下测定了巴基葱的电学特性 ,它表现为半导体特性 . A method to prepare onion-like graphitic particles was reported. Using a scanning probe microscope(SPM), we observed two micromorphology forms of as-prepared particles. Some of them are like bear sole, while the others resemble to calabash. All the particles arranged with axes tropism keeping in rigorous conformity, and some of them as strings. The causes, leading to the observed phenomena, were discussed. The electrical characteristics of the particles were measured at room temperature in ambient conditions and showed characteristic of semiconductor. |
