Abstract
The surface energies of monocrystalline (mc) and nanotwinned (nt) cadmium telluride (CdTe or CT) crystals, calculated using molecular dynamics simulations, are 435.08 and 381.8 mJ m−2, respectively. A crack of mc-CT is induced at the second loading cycle, whereas nt-CT with both twin boundaries (TBs) shows a crack at the lower TB under the third unloading condition. However, nt-CT with three TBs is free from cracks after 10 cyclic loading–unloading indentations, due to the combined effect between the hardening and softening nanotwins.
