Abstract: Nanoindentation measurements were performed for a single PbTe crystal grown by self-selecting vapour growth method and characterized by X-ray diffraction.The microhardness and Young's modulus were determined for a few loads applied along the [001], [011] and [111] high symmetry directions for carefully oriented, 2 mm thick crystal plates.An anisotropy of two parameters has been suggested and compared with available literature data.The present results qualitatively confirm the theoretical predictions for a rock salt type crystal (PbS).The microhardness anisotropy value is in an agreement with recently determined, relevant value for (Pb,Cd)Te solid solution.
