Low Dimensional Electronics and Mechanics
In this talk we review our recent progress in optically imaging on surface and suspended carbon nanotubes (CNTs).
This imaging technique is noninvasive and enables us to perform rapid device fabrication and characterization. We explore both the electrical and mechanical behavior of these CNTs. We report our observation of mechanical snap-through buckling bi-stability in suspended CNTs and explore their linear and non-linear behavior.
This bi-stability is a well-known phenomenon in micro-electromechanical systems (MEMS) which serves as the underlying mechanism for many practical applications such as switches, actuators, sensors, filters, and memory elements, to name a few. Finally, we developed a comprehensive theoretical model based on the Euler-Bernoulli beam theory to support our findings.
