“…The results calculated for transition pressures obtained by two methods and the relative volume changes ( V t /V 0 ) are listed in Table 2, together with the available experimental and other theoretical calculations to compare them. Our results for the transition pressure are in good agreement with those of a number resistivity [11,32], optical [33], X-ray absorption [12], X-ray diffraction [12,13,34] experiments ranging from 8.5 GPa to 10.0 GPa and 11.0 GPa to 13.0 GPa for B3 → B9 and B9 → B33 phase transitions, respectively. These values are also more compatible with the value predicted by Lee and Ihm [30] carrying out ab initio calculations in the framework of the DFT within the LDA than the previous works performing ab initio pseudo potential calculations [14,16].…”

“…The combined X-ray diffraction and electric resistivity study [11] has showed that the phase transition takes place at approximately 8.5 GPa to a nonmetallic hexagonal phase (ZnTe-II) and at about 13.0 GPa to metallic phase (ZnTe-III). However, their X-ray diffraction data is insufficient to determine the high pressure structures of ZnTe.…”

“…In 1980, A. Ohtani et al performed the resistance measurement of ZnTe and two discontinuities of resistance were found at 8.5 GPa and 13.0 GPa [5]. Two years later, similar result was reported by Endo's group [9].…”

“…Because of its scientific importance and high technological potential, ZnTe transportation property studies have attracted a stable attention. Since the first high pressure work on ZnTe by Samara and Drickamer [4], many studies have been conducted on property changes under high pressure by XRD [5][6][7], Raman [8] and electrical resistivity measurement [5,9,10].…”

The resistivity of ZnTe powders has been measured under high pressure up to 29 GPa and temperature ranged from 303.0 to 403.0 K by using a diamond anvil cell. The resistivity changed discontinuously at 9.5 and 13.1 GPa, corresponding to the phase transitions from zinc blende to cinnabar and then to Cmcm structure. The decrease of activation energy by one order of magnitude indicates the deep‐to‐shallow transition of acceptor levels at 6.7 GPa. The resistivity decreases with temperature increasing indicates the semiconducting character of ZnTe in zinc blende phase. The resistivity of ZnTe in cinnabar phase decreases slightly with temperature increasing, indicating that this phase is a narrow‐gap semiconductor. After 19.1 GPa, the resistivity increases with temperature increasing, indicating the metallic character of Cmcm phase. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…The application of pressure to the zinc-blende phase of ZnTe induces a transition at about 9 GPa into a semiconducting phase II and a second transition at about 12 GPa into a metallic phase III (Smith and Martin, 1965;Ohtani et al, 1980;Strö ssner et al, 1987). The structural characterization of these high-pressure phases eluded the best experimental efforts for several years.…”

High-pressure phases of group-IV, III–V, and II–VI compounds

et al. 2003

Advances in the accuracy and efficiency of first-principles electronic structure calculations have allowed detailed studies of the energetics of materials under high pressures. At the same time, improvements in the resolution of powder x-ray diffraction experiments and more sophisticated methods of data analysis have revealed the existence of many new and unexpected high-pressure phases. The most complete set of theoretical and experimental data obtained to date is for the group-IVA elements and the group-IIIA-VA and IIB-VIA compounds. Here the authors review the currently known structures and high-pressure behavior of these materials and the theoretical work that has been done on them. The capabilities of modern first-principles methods are illustrated by a full comparison with the experimental data. CONTENTS
