【Abstract】 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.更多还原
