Implication

Experimental study demonstrates thermal carrier activation and structural anomalies in bismuth-antimony alloys, suggesting band structure changes near twelve percent antimony.

Key Points

To examine how temperature and antimony concentration influence the electrical resistivity, Hall effect, and crystal lattice structure of bismuth-antimony alloys.
Synthesized zone-levelled single crystals of bismuth-antimony (Bi-Sb) alloys across the full solid-solubility range.
Measured electrical resistivity and Hall effect over temperatures ranging from 4.2 K to 300 K.
Determined crystal lattice parameters across the entire composition spectrum to identify structural changes.
Logarithmic resistivity curves indicated thermal activation of charge carriers between 25 K and 100 K for antimony concentrations of 5% to 40%, with activation energy peaking near 12% antimony.
Low-temperature anomalies in electrical resistivity and Hall effect were observed surrounding the 12% antimony concentration threshold.
Measurements of the c-axis lattice parameter revealed both a local maximum and minimum near the exact antimony concentration where transport anomalies occurred.
