Snap-through transition of buckled graphene membranes for memcapacitor applications

Abstract: Using computational and theoretical approaches, we investigate the snap-through transition of buckled graphene membranes. Our main interest is related to the possibility of using the buckled membrane as a plate of capacitor with memory (memcapacitor). For this purpose, we performed molecular-dynamics (MD) simulations and elasticity theory calculations of the up-to-down and down-to-up snap-through transitions for membranes of several sizes. We have obtained expressions for the threshold switching forces for bot… Show more

“…It should be noted that unlike the rigid plates mentioned above, the research on elastic plates has been on the rise in recent years. For instance, micro-curved plates can exhibit bistable behavior under appropriate driving force [103]. Although it is difficult to fabricate curved bistable microplates in the MEMS process, it is still a promising research direction.…”

“…Its movement is then governed by barrier crossing events and the vibrations shift to extremely low frequencies [ 16 , 17 , 18 , 19 ]. This area of research is in the early stages of development and is gaining attention for its potential applications [ 20 , 21 , 22 , 23 ].…”

“…Such a method could be used to control the path of electrons through multi-layered 2D structures by locally altering layer spacing, and with the resulting control over capacitance it offers a potential mechanism for voltage switching [35]. These results not only inform scanning probe measurements of graphene, but controlling local perturbations in graphene and other 2D materials is expected to lead to strain engineered materials [1].…”
