Abstract content <br> &nbsp; (Max 300 words)

The structural changes of glassy carbon (Sigradur® G) due to implantation with 360 keV strontium ions at room and high temperatures are reported. The samples were implanted with strontium ions at a fluence of 2×10¹⁶ ions/cm² at room temperatures, 350 °C and 600 °C. The influence of ion implantation on surface morphology and topology was examined by the scanning electron microscopy (SEM) and atomic force microscope (AFM). Raman spectroscopy and X-ray diffraction were used to monitor the structural changes induced in glassy carbon as a result of implantation. The depth profiles of the strontium implanted at different temperatures we determined by Rutherford backscattering (RBS).
