Stress induced delamination of suspended MoS2 in aqueous environments

Aleksandra Radenovic, Mukeshchand Thakur, Sanjin Marion, Michal Daniel Macha

Applying hydrostatic pressure with suspended 2D material thin membranes allows probing the effects of lateral strain on the ion and fluid transport through nanopores. We demonstrate how both permanent and temporary delamination of 2D materials can be induc ...
