Steep-slope hysteresis-free negative capacitance MoS2 transistors
Nature Nanotechnology, 2017The so-called Boltzmann tyranny defines the fundamental thermionic limit of the subthreshold slope of a metal–oxide–semiconductor field-effect transistor (MOSFET) at 60 mV dec−1 at room temperature and therefore precludes lowering of the supply voltage ...

Recent Progress on High‐Capacitance Polymer Gate Dielectrics for Flexible Low‐Voltage Transistors
Advanced Functional Materials, 2018The gate dielectric layer is an essential element of field‐effect transistors (FETs), large area integrated circuits, and various application electronics. Beyond basic insulation between the semiconductor layer and gate electrode, FET performance largely
