Probing interfacial interactions of ions with molecular layers at the electrolyte-semiconductor interface by using an ionic diffusion-driven ionvoltaic transducer |
| 초록 |
Electrolyte-semiconductor interactions are the fundamental principles of various electrochemical systems and electrolyte-driven energy conversion devices, but corresponding details remained unrevealed. Herein, an ion-charge carrier interaction was interrogated with an ion-dynamics-induced (ionovoltaic) energy transducer, controlled by interfacial molecular layers. An electricity generating mechanism from interfacial ionic diffusion was elucidated in terms of the ion-charge carrier interaction, originating from a dipole potential effect of the self-assembled molecular layer (SAM). Through the surface modification and transition metal ion complexation, this effect could be modulated and demonstrated by monitoring the electrical behaviors of the device with the aiding of surface analytic techniques and a liquid-interfacing Hall measurement. Hence, this system could apply to study physical and chemical ion-molecular interactions occurring at the electrolyte-SAM-semiconductor interface. |
