Abstract
The well aligned InZnP:Ag nano-rods doped with noble metal Ag were fabricated using ion milling method. Results for XPS coincide with results for AES, especially Ag 3d5. The uniformity, density, and height of InZnP:Ag nano-rods were well formed in TEM measurements. In order to clarify the formation of InZnP:Ag nano-rods, SEM was carried out due to the doping of Ag. XRD measurements were performed in order to support the above TEM results, it is confirmed that the lattice was well aligned without distortion and that the nano-rod was a single crystalline zinc blende structure. The variation of FWHM for TAD peaks demonstrates that noble metal Ag is incorporated into InZnP:Ag nano-rods. The trend of FWHM results coincides with the trend of TEM results according to ion milling depth. The clear opening of the ferromagnetic hysteresis loop indicates the formation of ferromagnetic spin coupling interaction in InP:Zn doped with Ag. The FC M-T curve clearly displays that the ferromagnetism of InZnP:Ag persists near 300 K. (C) 2017 Elsevier B.V. All rights reserved.
