Charge transfer in the nanoscale and SERS: understanding the huge efficiency of the electrode potencial in tuning the CT states
Centeno-Benigno, Silvia Patricia
; Ruano, Cristina; Roman-Perez, Jessica; López-Tocón, Isabel; Soto-Martín, Juan; Otero-Fernández-de-Molina, Juan Carlos[et al.] (2014-09-10)
This work deals with the unexplained efficiency of the electrode potential in tuning the energy of the CT states of hybrid systems formed by molecules and metallic nano structures. Huge energy gain up to 5eV/V observed in ... -
Effect of the electrode potential on surface-enhanced Raman intensities of 2-methylpyrazine
López-Tocón, Isabel; Centeno-Benigno, Silvia Patricia; Roman-Perez, Jessica; Otero-Fernández-de-Molina, Juan Carlos (2014-05-30)
The effect of the electrode potential on Surface Enhanced Raman Scattering (SERS) intensities of 2-methylpyrazine (2MP) recorded under resonant charge transfer (CT) conditions is analyzed by using a simple theoretical model ... -

Using SERS to probe electric capacitive enhancement in nanometer-size hot spots
Centeno-Benigno, Silvia Patricia; Ruano, Cristina; Roman-Perez, Jessica; López-Ramírez, Jéssica; Soto-Martín, Juan; Otero-Fernández-de-Molina, Juan Carlos[et al.] (2014-09-10)
Although the electromagnetic mechanism related to localized plasmons of the metal is the most important contribution in SERS, the chemical interaction between metal and molecule plays a crucial role. In SERS electrochemical ... -
Using Surface-enhanced Raman scattering to probe the capacitance of metallic nanostructures
Centeno-Benigno, Silvia Patricia; Ruano, Cristina; Roman-Perez, Jessica; López-Tocón, Isabel; Otero-Fernández-de-Molina, Juan Carlos; Soto-Martín, Juan[et al.] (2013)
Though it is generally accepted that the electromagnetic mechanism related to the excitation of localized plasmons of the metal surface is the most important contribution in SERS, the chemical interaction between molecule ...
