Pastor, María Jesús ; Sánchez, Ignacio ; Campo, José A. ; Schmidt, Rainer ; Cano, Mercedes | MDPI | 2018-04Ionic liquid crystals (ILCs) are a class of materials that combine the properties of liquid crystals (LCs) and ionic liquids (ILs). This type of materials is directed towards properties such as conductivity in ordered systems at different temper[...]![]()

Frechero, M. A. ; Rocci, Mirko ; Sánchez Santolino, Gabriel ; Salafranca, Juan ; Schmidt, Rainer ; Díaz Guillén, M. R. ; Durá, O. 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[...]![]()

Fiorenza, Patrick ; Lo Nigro, Raffaella ; Raineri, Vito ; Schmidt, Rainer ; Sinclair, Derek | IOP Publishing | 2010Scanning probe microscopy (SPM) with conductive tips has been used to image the dielectric properties of ceramics with giant permittivity. In particular, measurements in impedance mode of local resistivity allowed to image the permittivity map o[...]![]()

Ramírez, J. G. ; Schmidt, Rainer ; Sharoni, A. ; Gómez, M. E. ; Schuller, Ivan K. ; Patiño, Edgar J. | American Institute of Physics | 2013-02-11Temperature dependent dielectric spectroscopy measurements on vanadium dioxide thin films allow us to distinguish between the resistive, capacitive, and inductive contributions to the impedance across the metal-insulator transition (MIT). We dev[...]
