Weba semiconductor with an indirect gap (like silicon (Si)) a semimetal (like tin (Sn) or graphite and the alkaline earth metals ). The figure is schematic, showing only the lowest-energy conduction band and the highest-energy valence band in one dimension of momentum space (or k-space). step program army 2021Pure 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… stepp program cdpheWebBismuth-based double perovskite Cs 2 AgBiBr 6 is regarded as a potential candidate for low-toxicity, high-stability perovskite solar cells.
