Antimony-contact MoS2 FET gas sensors for reinforcement-learning–driven hazard perception at room temperature

Two-dimensional van der Waals semiconductors promise low-power chemical perception at room temperature, yet contact-limited on-currents and slow recovery impede closed-loop decision making in hazardous environments. Here we propose antimony (Sb)-contact two-dimensional (2D) monol...

Sub-Coercive Analog Conductance Modulation from Distributed Energy Barriers in Semicrystalline Ferroelectric Polymer Transistors

Ferroelectric switching is understood as a nucleation-limited process, in which polarization domains switch abruptly once the applied electric field exceeds a well-defined coercive field (Ec). However, the macroscopic Ec is an incomplete descriptor in semicrystalline ferroelectri...
