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 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.
