  • Negative capacitance (NC) is a promising route towards low-power electronics. Here, a theory clarifying the connection between NC and voltage amplification is presented, and it is predicted that incipient ferroelectric states that do not necessarily maximize NC can result in a tenfold voltage amplification.
