Expérimental Description
Biology processes information with ions flowing through nanochannels. Artificial nanofluidic devices made from 2D materials such as graphene now show ionic memory, which recent optical observations attribute to voltage-induced deformation of the channels. The physics behind this deformation remains poorly understood. In this internship, the student will fabricate model devices, submerged 2D flakes on substrates, and measure how the electrostatic pressure competes with interlayer adhesion, using coupled optical and electrokinetic measurements. Tuning the substrate roughness will then allow control of adhesion. The goal is a quantitative model identifying the key parameters for designing ionic memories.
