| Abstract: | Indium phosphide (InP) semiconductor nanoparticles were obtained by laser ablation of a crystalline wafer in water. The transmission electron microscopy micrographs of the nanoparticles show that their size is in the range of 100 nm. In the Raman spectrum of the nanoparticles, the characteristic peaks of InP have been observed in the vicinity of 300 and 340 cm−1. The binding energies as measured from the X-ray photoemission spectra are consistent with values for InP crystal as well as indium oxides. |
