Abstract
Implantation of the (110)-oriented surfaces of CdTe single crystals, chemically polished in a bromine-ethylene glycol-dimethylformamide solution, with 500 keV Cr+ ions at fluences of 1016, 1017, and 5⋅1017 cm−2 was performed. Investigations using various experimental methods showed that implantation significantly alters the surface morphology, structure, and phase composition, depending on the applied fluence. Upon ion bombardment, the surface topography becomes coarser and rougher, evolving into a highly eroded pattern at the highest fluence due to prolonged irradiation-induced sputtering. In parallel, an improvement in surface crystallinity was observed after removal of the amorphous, tellurium oxide-enriched top layer formed during polishing. Structural disordering and precipitation of Cr-Te phases were detected in the near-surface layer as the fluence increased to 5⋅1017 cm−2. This behavior is attributed to a shift of the surface toward the region of damage buildup and dopant aggregation, induced by irradiation under sputter equilibrium conditions. However, even at the highest dose, no amorphization was observed, suggesting that the CdTe lattice is highly resistant to degradation under bombardment by medium-energy Cr+ ions. The results demonstrate the potential of ion implantation for fabricating a composite consisting of a CdTe semiconducting matrix with embedded Cr-Te ferromagnetic nanoprecipitates, which could have spintronic applications.
