Abstract: The thin layers of (Sn,Mn)Te solid solution were grown by molecular beam epitaxy onto (111)-oriented BaF2 substrates and characterized by scanning electron microscopy, atomic force microscopy, energy dispersive X-ray spectrometry, and X-ray diffraction methods.The epitaxial character of the growth was confirmed.All the layers exhibited a regular (fcc) structure of the rock-salt type and were (111)-oriented, their thickness was close to about 1 µm.The layers contained up to 8% of Mn.The microhardness and the Young modulus values were determined by the nanoindentation measurements.The Berkovich type of the intender was applied, the maximum applied load was equal to 1 mN.The results of measurements demonstrated a lack of the composition dependence of the Young modulus value.A slight increase of the microhardness value with an increasing Mn content in the (Sn,Mn)Te solid solution was observed.
