Using AdS/CFT, we investigate the influence of chemical potential on the holographic Schwinger effect at finite temperature. We study the potential barrier for the pair production and calculate the critical electric field by Dirac-Born-Infeld (DBI) action. It is found that the chemical potential decreases the potential barrier thus enhancing the Schwinger effect.
