Description	Sklovitý karbon byl implantován ionty 150 keV Co+, nízkou dávkou 1x10(16) a vysokou dávkou 1x10(16)iontů/cm(2). Byly studovány výsledné strukturální změny. (cs) Glassy carbon (GC) was implanted by 150 keV Co+ ions to the doses of 1x10(16) (low dose) and 1x10(17) ions/cm(2) (high dose). The low dose implantation results in GC structure disordering with formation of amorphous carbon (a-C). Analysis of Rutherford backscattering (RBS) and Raman spectra has revealed 15 at.% of sp(3)-bonded C atoms in the a-C structure. The in-pane size of sp(2) clusters was estimated to be 1.1 nm. On the contrary, the high dose ion implantation results in ordering of the a-C structure. Content of the sp(3) atoms in a-C was reduced to about 5% and, respectively, the in-plane sp(2) cluster size was increased up to 2.8 nm. Together with the a-C structure ordering the Raman spectra identifies formation of transpolyacetylene (TPA)-like chains after the high-dose Co+ implantation. In parallel, RBS suggests an enhanced diffusion of the implanted cobalt within the modified carbon layer.
