Mechanics of defective 2D materials - img2D semiconductor materials, specifically Transition Metal Dichalcogenides (TMDCs), are emerging as key players in the development of future flexible electronic devices. Their exceptional mechanical strength and adjustable electronic bandgap make them promising candidates for various applications. However, ensuring the mechanical reliability of these materials is crucial for their successful integration into flexible electronics. This reliability can be limited by factors such as ultimate tensile strength, fracture toughness, and fatigue resistance.
In this talk I will show our work on evaluating the reliability of real life 2D materials, where the presence of atomic defects is inherent. I will present our recent studies on mechanical response of MoS2 with systematically and controllably created atomic vacancies.
Our findings shed light on strategies to enhance the mechanical reliability of 2D semiconductor materials, paving the way for their effective utilization in future flexible electronics.
