摘要

We have investigated the behavior of red mercuric iodide (alpha-HgI2) under high pressures using in situ X-ray diffraction and optical absorption techniques. Our experimental results indicate that the tetragonal --> orthorhombic phase transformation, observed at 1.4 GPa, is accompanied by an abrupt increase in the band gap while the nature of the gap does not change. However, across the orthorhombic --> hexagonal phase transformation, observed at similar to 7.2 GPa, the gap decreases discontinuously and changes from direct to indirect type. These studies suggest that HgI2 may metallize at similar to40 GPa, if not prevented by any other structural change. (C) 2004 Elsevier Ltd. All rights reserved.
