Microstructural Study of Fe-Implanted SiC: Comparison of Different Post-Implantation Treatments

Authors: Alain Declémy, Cyril Dupeyrat, Lionel Thomé, Aurelien Debelle

Abstract: Silicon carbide (SiC) could be a good candidate for Diluted Magnetic Semiconductor (DMS). In this paper we report on preliminary results on the microstructure of Fe-implanted 6H-SiC subsequently submitted to Rapid Thermal Annealing (RTA), laser processing in the solid phase and swift heavy ion irradiation and analyzed by means of X-ray diffraction (XRD) and Rutherford backscattering and channeling (RBS/C).

Ferromagnetic Property of Co and Fe-Implanted ZnO Thin Film at Room Temperature

Authors: W.K. Choi, Basavaraj Angadi, H.C. Park, J.H. Lee, Jong Han Song, Ravi Kumar

Abstract: The results Co and Fe implanted ZnO thin films were studied before and after 200 MeV Ag ion irradiation. The as-implanted films shows the presence of nano sized Co and Fe clusters as seen through XRD patterns and exhibited high resistivity compared to un-implanted films. After Ag ion irradiation the Co and Fe clusters get dissolved in ZnO lattice and the films resistivity reduced to half of the as implanted values. The magnetic properties of Ag irradiated films were confirmed through magnetization hysteresis and Co implanted films exhibit higher magnetization compared to Fe implanted films.
