For the same applied uniaxial strain, a longer contraction is found in the perpendicular direction. Further, the value of Poisson's ratio is the lowest for CrS 2 suggesting it as an effective material to resist the external shear force as compared to other monolayers. To confirm this fact, we evaluated the shear modulus for each monolayers (Table ). The highest value of shear modulus for CrS 2 validates the result of Possion's ratio. In addition, the highest value of for CrS 2 suggests it as the most resilient monolayer for stretching.
