Viva Horowitz

Assistant Professor of Physics Viva Horowitz co-authored a paper that was recently published in the journal Micromachines. She and several researchers from the University of Oregon presented the results of their work in “Coupled Nanomechanical Graphene Resonators: A Promising Platform for Scalable NEMS Networks.”

The group says that “arrays of coupled nanoelectromechanical resonators are a promising foundation for implementing large-scale network applications, such as mechanical-based information processing and computing, but their practical realization remains an outstanding challenge.” In their work, they demonstrated a scalable platform of suspended graphene resonators, which they say can serve as “a viable option for realizing large-scale programmable networks, enabling applications such as phononic circuits, tunable waveguides, and reconfigurable metamaterials.”

As a nanoscientist, Horowitz worked on the fabrication and interpretation of what she describes as “tiny trampolines.” She says the system in which they are used is “a lot like a trampoline park, with a bunch of trampolines all next to each other, with an array of columns holding the whole thing.” The researchers used a pump laser as a “little jumper” jumping on the trampoline and making it resonate. They then explored the shape of that resonance using a less powerful probe laser.

Horowitz and her co-authors say this is a promising and scalable NEMS (or nanoelectromechanical system), noting that the design could be useful for engineering a mechanical system for use in mechanical-based information processing and computing.

Horowitz, who has worked with mechanical resonators for some time, adds that they “are also useful for developing metamaterials that transmit sound in specialized ways.”

The $400 million campaign marked the most ambitious fundraising initiative in the College's history.
