Development of novel tensile test method for low-dimensional brittle nanomaterials |
| 초록 |
As components of modern-day electronics shrink into nano/micro-size, miniaturization of materials to corresponding nanoscale while maintaining the similar level of electronic and mechanical standards as their bulk counterpart also became an essential part of the fabrication. Particularly, in applications like nanomechanics, understanding the mechanical properties of brittle nanomaterials is very imperative due to the noticeable discrepancy in material properties between bulk and nano scale. Using Micro-Electromechanical System Push-to-Pull (MEMS-PTP) devices for the examination of mechanical properties of brittle nanomaterials is prevalent owing to their compliant components which help them sway in a desired direction by the PTP mechanism. However, such a helpful mechanism comes with few drawbacks such as extremely fragile nature of complaint beams and incapability to capture the abrupt brittle failure behavior. Therefore, this research attempts to suggest a novel experimental method to catch the mechanical instability of brittle nanomaterials as well as to reduce the chances of pre-test failure with the help of several structured engineering barriers. The validity of this research has been confirmed by a test experiment with a graphene sample. The implication of this research can include, but not limited to 2D Transition Metal Dichalcogenide (TMD), heterogeneous nanocomposites and many other low dimensional materials for nano-scale applications. |
