초록 (요약문)
An ion transistor incorporating an asymmetric nanochannel network membrane (NCNM), assembled through nanoparticle self- organization, demonstrates distinct four-phase ionic switching behavior with a high amplification factor. Despite these promising characteristics, a comprehensive evaluation of its performance across different ionic species and geometric configurations remains lacking. In this work, we systematically investigate the influence of monovalent and divalent cations (K⁺, Li⁺, Ca²⁺) as well as variations in device geometry on the clarity of four-phase transitions and amplification behavior. By integrating experimental characterization with multiphysics numerical simulations, we provide a comparative analysis that elucidates the respective contributions of ionic composition and structural design to the transistor's functional performance. These findings offer new insights into the design principles governing iontronic devices for next- generation neuromorphic and sensing applications.
