Bi4O4S3 was the first superconductor discovered
in the BiS2 family of novel superconductors. The subfamily
of Bi-O-S systems now expanded andwas probed both theoretically
and experimentally. Here we review the experimentalwork
done on the Bi-O-S compounds, and compare
it with theoretical results obtained using ab-initio methods.
In particular we calculate the charge carrier density
using an ab-initio calculated density of states, and find a
really close agreement with experimental data.
