J. ; Rivera Calzada, Alberto Carlos ; Varela del Arco, María ; Santamaría Sánchez-Barriga, Jacobo ; León Yebra, Carlos | Nature Publishing Group | 2015-12-17The blocking of ion transport at interfaces strongly limits the performance of electrochemical nanodevices for energy applications. The barrier is believed to arise from space-charge regions generated by mobile ions by analogy to semiconductor j[...]texto impreso
