Orientation-Independent Yield Stress and Activation Volume of Dislocation Nucleation in LiTaO<sub>3</sub> Single Crystal by Nanoindentation

Orientation-Independent Yield Stress and Activation Volume of Dislocation Nucleation in LiTaO<sub>3</sub> Single Crystal by Nanoindentation

Relying on nanoindentation technology, we investigated the elastic-to-plastic transition via first pop-in event and estimated the corresponding shear stress for incipient plasticity, i.e., yielding in the three typical orientations, i.e., X-112&#176;, Y-36&#176;, and Y-42&#176; planes. T...
