We study the quantum stability of a tachyon field in the two-dimensional (2D),
charged black holes. In particular, the stress - energy tensor
observed by a freely falling observer has new divergences such as
and
near the horizon
, compared with conformal matter. It turns out that both the extremal and non-extremal black holes are unstable quantum mechanically.
