Negative Capacitance in HfO2 Gate Stack Structures With and Without Metal Interlayer

Mihai Adrian Ionescu, Igor Stolichnov, Ali Saeidi, Eamon Patrick O'Connor, Francesco Bellando, Matteo Cavalieri, Carlotta Gastaldi

In this work, we experimentally explore and compare FET gate stacks with and without an inner metal plane between a linear dielectric (SiO2) and a ferroelectric layer (Si-doped HfO2) operating in the negative capacitance (NC) regime. The use of nanosecond- ...

Lock-in amplified differential phase contrast

Christophe Moser, Timothé Laforest, Damien Claude-Marie Loterie, Chiara Bonati

We introduce a lock-in method to increase the phase contrast in incoherent Differential Phase Contrast (DPC) imaging. The use of a smart pixel detector with in-pixel signal demodulation, paired with synchronized illumination, provides the basis of a bit-ef ...
