Computational study on the effect of aspect ratio on Young’s modulus of boron nitride nanosheets

Abstract

The effect of the aspect ratio on Young’s modulus (E) of boron nitride nanosheet (BNNS) was studied using molecular dynamics simulation techniques employing the Tersoff potential field. The aspect ratio (L/B) of BNNS may influence the elastic properties; therefore, the values are varied from 2 to 12. Our results revealed that the E of BNNS decreased with an increase in the aspect ratio up to 9 and then became stable in both armchair and zigzag directions. It is anticipated that the result will provide a beneficial understanding of the elastic properties of BNNS which can aid in the design and implementation of structured and tailored nanoelectromechanical devices, transistors, sensors, ultralight-weight materials and automotive sectors.
