Two-Dimensional Fractal Structures of Metal Oxides Synthesized at Room Temperature
2D metal oxide fractal structures with different appearance and composition are successfully grown on the silicon (100) substrates from their colloidal solutions at room temperature. These films display very high surface coverage on the substrates and abundant structures. The results demonstrate the appearances and dimensions of these structures are dependent on the properties and composition of their constituent particles and the substrates. This work may have potential applications in the fabrication of gas sensors, photon-receivers and catalyst carriers which are not easy made by other methods at RT.
