Abstract We investigate the charged scalar pair production near the horizon of a near-extremal Kerr-Sen black holes. The condition for pair production to occur has relation to the violation of Breitenlohner–Freedman bound in an $$\hbox {AdS}_2$$ AdS2 space. The method employed in this work has been used to show the pair production in the near-horizon of a near-extremal Kerr–Newman black hole and its non-rotating case as well. We also discuss the static limit of our result.
