| Description |
The effect of quasi-hydrostatic pressure up to 2000 MPa on the temperature dependence of the electrical resistance is investigated in polycrystalline bismuth antimony (Bi-Sb) alloys containing 10, 12 and 15 at. % antimony. The results obtained indicate semimetallic phase under pressure for the alloys with antimony content of 10 and 15 at. %. The alloy with 12 at. % antimony changes its phase from semiconducting to semimetallic (SC→SM) under pressure. These pressure induced electronic transitions from SC→SM are due to basic changes in the energy spectrum occurring with the disappearance of electron and hole constant energy surfaces.
