Non-Destructive Studies in Hexagonal Nanocrystalline ZnO and BeO Semiconductors

S. Tahir Husen


Abstract: In the current work we, investigate the elastic, mechanical, thermal and also the ultrasonic properties of nanocrystalline ZnO and BeO semiconductors at room temperature. These semiconductors have hexagonal structure and exhibit semiconducting nature. Theoretically we found that BeO has mechanical properties superior to those of ZnO. The elastic properties (second-and third order elastic coefficients) have been evaluated using Lennard-Jones potential. The elastic property of BeO is improved than those of ZnO, since ZnO have lower values of elastic coefficients. The ultrasonic properties like ultrasonic attenuation & sound velocity in these semiconductors have been studied in different directions at room temperature. We calculated the ultrasonic velocity in different directions and came to conclusion that these semiconductors are anisotropic.
