December 8th, 2020 - Eric Parsonnet of UC Berkeley Gives a Big Thanks to BNC.

Thanks to the high-speed BN (Model) 765 pulse generator from Berkeley Nucleonics, we were able to access timescales very rarely accessed in pulsed, voltage-current measurements. With their product and excellent support, we successfully developed and built a new experiment and experimental protocol leading to a novel publication on limits for switching BiFeO3, a promising material for next-generation computer architecture. The paper is published in Physical review letters. We could not have done it without the fantastic team at Berkeley Nucleonics!

ABSTRACT
Using pulsed ferroelectric measurements, we probe switching dynamics in multiferroic BiFeO3, revealing low-ns switching times and a clear pathway to sub-ns switching. Our data is well described by a nucleation and growth model, which accounts for the various timescales in the switching process, namely (1) the ferroelectric polarization switching (bound-charge) dynamics and (2) the RC-limited movement of free charge in the circuit. Our model shows good agreement with observed data and begins to bridge the gap between experiment and theory, indicating pathways to study ferroelectric switching on intrinsic timescales.
