Dipolar excitons are bound states of spatially separated electrons and holes. It has been predicted that these composite bosons may undergo a phase transition to a condensate state and that this state has the potential to be engineered into switching devices. In this talk, we will present a historical overview of the field, and then focus on manifestations of this phenomenon in two-dimensional materials such as graphene, and one-dimensional systems such as core-shell nanowires.
