Journal ArticleDOI
Highly Flexible Hybrid CMOS Inverter Based on Si Nanomembrane and Molybdenum Disulfide.
TL;DR: The fabricated hetero-CMOS inverters which are composed of two isolated transistors exhibit a novel high performance air-stable voltage transfer characteristic with different supply voltages, with a maximum voltage gain of ≈16, and sub-nano watt power consumption.
Journal ArticleDOI
