Estimating the term…
Some embodiments relates inter alia to a method for controlling a work function of at least one surface comprising: measuring a first work function of a first surface; depositing a chiral system on the first surface to cause change in the first work function; applying a potential difference between the first surface and a second surface, such that to create a charge transfer between the first and second surfaces; measuring a second work function of the first surface carrying the chiral system; wherein the second work function is lower than the first work function. The interaction between the chiral system and the first surface is configured for causing charge rearrangement, spin polarization of the surface, and spin polarization of electrons being injected from or to the first surface, thereby modifying the work function of the first surface. The present disclosure also relates to electrodes, electrochemical cells, energy storage devices, photovoltaic cells, and electrical components, thereof.
A method for controlling a work function of at least one surface comprising:
An electrode for use in an electrochemical process comprising a substrate having an electrically conductive surface carrying a chiral system, wherein said chiral system is configured for controlling a work function of the electrode by application of a potential difference between said electrically conductive surface and a second surface thereby creating a charge transfer between said electrically conductive surface and the second surface, interaction between said chiral system and said electrically conductive surface causing charge rearrangement, spin polarization of the electrically conductive surface and spin polarization of electrons being injected from or to the electrically conductive surface so as to reduce the work function of the electrode, the potential for starting the electrochemical process and the electrical internal resistance of the electrode.
