© The Author(s) 2014. Published by ECS. An effective method to improve the thermal stability of Ni(Ge 1-x Sn x ) by carbon pre-stanogermanidation implant into GeSn substrate is investigated systematically. As-prepared samples were characterized by means of sheet resistance measurement, X-ray diffraction (XRD), scanning electron microscopy (SEM), cross-sectional transmission electron microscopy (X-TEM) and secondary ions mass spectroscopy (SIMS). The incorporation of carbon leads to significantly improved thermal stability of Ni(Ge 1-x Sn x ) by about 100.C as well as tends to change the preferred orientations of polycrystalline Ni(Ge 1-x Sn x ). The robust thermal stability can be attributed to the segregation of C in grain boundaries and at Ni(Ge 1-x Sn x )/GeSn interface after stanogermanidation.
