The first successful theory of superconductivity was the one proposed byBardeen, Cooper and Schrieffer in 1957. This breakthrough fostered a remarkablegrowth of the field that propitiated progress and questionings, generatingalternative theories to explain specific phenomena. For example, it has beenargued that Bismuth, being a semimetal with a low number of carriers, does notcomply with the basic hypotheses underlying BCS and therefore a differentapproach should be considered. Nevertheless, in 2016 based on BCS we put fortha prediction that Bi at ambient pressure becomes a superconductor at 1.3 mK[1]. A year later an experimental group corroborated that in fact Bi is asuperconductor with a transition temperature of 0.53 mK [2], a result thateluded previous work. So, since Bi is superconductive in almost all thedifferent structures and phases, the question is why Bi-IV has been elusive andhas not been found yet to superconduct? Here we present a study of theelectronic and vibrational properties of Bi-IV and infer its possiblesuperconductivity using a BCS approach. We predict that if the Bi-IV phasestructure were cooled down to liquid helium temperatures it would alsosuperconduct at a Tc of 4.25 K.
