is: a material containing a relatively small but significant number of mobile charged particles. [P4.1, P11.4]
has: a resistivity between that of good conductors (i.e. metals) and insulators, most typically in the range
to
[P4.1, P11.4]
has typically: in terms of band theory of solids, at absolute zero, an empty conduction band at a gap
or less above a full valence band. [P11.4]
is exemplified: by silicon and germanium, which are used for the construction of electronic devices. [P4.1]
