Electrostatic Gating of Ionic Conductance Through Heterogeneous van der Waals Nanopores
Aaron H. Barajas-Aguilar, Matthew Schiel, Ethan Cao +6
Nanofluidic ionic transistors typically require gate voltages above 1 V and operate only at sub millimolar ionic strengths, limiting their biocompatible applications. We demonstrat…

Manipulating moires by controlling heterostrain in van der Waals devices
Ian Sequeira, Andrew Z. Barabas, Aaron H Barajas-Aguilar +6
Van der Waals (vdW) moires offer tunable superlattices that can strongly manipulate electronic properties. We demonstrate the in-situ manipulation of moire superlattices via hetero…

Electrically-driven amplification of terahertz acoustic waves in graphene
Aaron H. Barajas-Aguilar, Jasen Zion, Ian Sequeira +6
In graphene devices, the electronic drift velocity can easily exceed the speed of sound in the material at moderate current biases. Under this condition, the electronic system can…
