Bismuth room temperature
Pure bismuth is a semimetal, containing a small band gap, which leads to it having a relatively high conductivity (7.7×10 S/m at 20 °C). When the bismuth is doped with antimony, the conduction band decreases in energy and the valence band increases in energy. At an antimony concentration of 4%, the two bands intersect, forming a Dirac point (which is defined as a point where the conduction and valence bands intersect). Further increases in the concentration of an… WebMar 28, 2024 · Bismuth ferrite (BiFeO 3, BFO) has been found to have a ferroelectric phase transition Curie temperature (T C) of 1103 K and a G-type antiferromagnetic …
