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...

Defect-mediated generation–recombination dynamics governing conductance response in floating-body transistors

As CMOS technologies evolve toward ultra-thin floating-body architectures, defect-mediated carrier dynamics increasingly dominate device behavior, challenging conventional linear interpretations of electrical response in nanoscale transistors. In this work, we demonstrate that th...
