We synthesize Ti–PS nanocomposites by plasma immersion ion implantation and deposition (PIII&D) technique. Ti nanoparticles at size of 5–15nm are found in PS matrix. We propose the formation of Ti nanoparticles as a result of the combined effect of ion implantation and ion condensation in PIII&D process. X-ray photoelectron spectroscopy measurements reveal that Ti atoms have three different...
Surface defects passivation of ZnO nanocombs was performed through a Ti plasma immersion ion implantation (PIII) with low bias voltages ranging from 0-10 kV. The room temperature near-band-edge emission was enhanced for modified ZnO nanostructures while the defect-related green band was completely quenched. Detailed temperature dependence PL revealed that the deep-level emissions were surface related...
Using ultrasharp conductive tip atomic force microscopy (c-AFM), we have measured the current voltage (I-V) characteristics of titanium ions implanted into polystyrene thin film spin coated onto silicon substrate. The surface morphology and the electric current between the tip and sample have been obtained simultaneously on the nanometer scale. Initial island-like growths structures were observed...
