Study of the electronic, bonding, elastic and acoustic properties of covellite via first principles
文摘

LDA and GGA-PBESOL are found suitable for studying properties of covellite.

Calculated electronic properties explain the corresponding experimental findings well.

Studies show that covellite is mechanically stable but anisotropic.

Close relation exists between C44 and the c-axis easy-cracked property of covellite.

Slowness curves are computed and discussed to investigate the acoustic properties.
