Notes:
The microhardness H of the AIBIIIC2VI chalcopyrites can be estimated from the bulk modulus B0 by using a simple scaling law. Values of B0 for these compounds, obtained from energy dispersive x-ray diffraction and x-ray absorption spectroscopy techniques under high pressure, have been used in the scaling. The pressure-induced phase transformation from the chalcopyrite to denser structures, observed in these compounds, is also discussed. A relationship between H and the critical pressure at which such a transition occurs is also obtained. © 1999 American Institute of Physics.
