  Most of our current knowledge on condensed matters contains a default
assumption: the matters are neutral charged. On the other hand, the
two-dimension(2D) vortex-Coulomb gas charge analogy is a very successful
theoretical tool in explaining superfluid, type-II superconductor and
fractional quantum Hall effect(FQHE), because the interaction among vortices
show similarity with 2D Coulomb potential. Here, by breaking the 'neutral
charged' assumption, we suggest the positively charged 2D semiconductor system
can possess non-trivial particle-like charge centers(called 'quasihole'), which
is the charge version of 'vortex'. Using the hypernetted-chain (HNC)
approximation, the structure of quasihole is elucidated. Numerical calculations
show that the quasihole can be projected onto another 2D layer, producing an
electric field configuration characterized by 3/2 topological charge.
