Strategic Fermi Level Engineering of Donor-Acceptor Self-Assembled Monolayer toward Ultrahigh Paired-Pulse Facilitations in Photosynaptic Transistors.

ABSTRACT: Given the rapid advancement of artificial intelligence and the demand for low-power computing, photosynaptic transistors have emerged as promising candidates by integrating sensing, memory, and processing to mimic biological synapses. However, simultaneously realizing high paired-pulse facilitation (PPF) and low energy consumption in an artificial synapse, as biological ones, remains challenging. This property should be achieved by balancing the high carrier density while maintaining a low conductivity in the photoresponsive/charge-trapping electret; however, these prerequisites are mutually contradictory. To achieve this goal, a series of electron acceptors, 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F₄TCNQ), tris(pentafluorophenyl)borane (BCF), and their Lewis-paire
