Abstract: Nanotwinned (nt) mercury cadmium telluride (HgCdTe or MCT) was prepared using nanoindentations. The hardness of nt-MCT is 100 times higher than that of monocrystalline counterparts. Transmission electron microscopy shows that the twin lamellae of nt-MCT prior to cyclic nanoindentations are distributed along two directions, intersecting at an angle of 76 degrees. The nanotwinned microstructure of nt-MCT is stable after 100 cyclic nanoindentations. The loading-unloading curves of nt-MCT are basically invariable after 50 cycles, and have elastic characteristics. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
