Multivalued Logic and Encryption Based on Anti‐Ambipolar Transistor Dynamic Controlled by Light and Temperature

ABSTRACT Anti‐ambipolar transistors (AATs) show great potential to improve the performance of ternary logic circuits and the areal computing density. Beyond developing the environmental adaptability of AATs, exploring the synergistic modulation mechanisms and modulating 1/2 state through external environment signals offers new insights for the specific‐application of multivalued logic devices. In this study, reconfigurable organic AATs are developed, constructed from an asymmetric p‐n heterojunction architecture. The dynamic carrier's distribution near the vertical interface with gate voltage changing resulted in the channel current non‐monotonic behavior. The light‐induced photocarrier generation and thermally enhanced charge transfer enabled light‐temperature antagonistic operations on the dynamic control of 1/2 state. The specific pair of optical intensity and temperature could be set as the independent “key” to activate the encrypted 1/2 state, a portable decryption framework based on the puzzle‐style optical encoding and thermal decoding strategy is implemented in encrypted binary images that enhance the information security confidentiality in specified environment.
