High elasticity and strength of ultra-thin metallic transition metal dichalcogenides.

ABSTRACT: Mechanical properties of transition metal dichalcogenides (TMDCs) are relevant to their prospective applications in flexible electronics. So far, the focus has been on the semiconducting TMDCs, mostly MoX₂ and WX₂ (X = S, Se) due to their potential in optoelectronics. A comprehensive understanding of the elastic properties of metallic TMDCs is needed to complement the semiconducting TMDCs in flexible optoelectronics. Thus, mechanical testing of metallic TMDCs is pertinent to the realization of the applications. Here, we report on the atomic force microscopy-based nano-indentation measurements on ultra-thin 2H-TaS₂ crystals to elucidate the stretching and breaking of the metallic TMDCs. We explored the elastic properties of 2H-TaS₂ at different th
