The Young’s Modulus of Silicon Nitride Ceramics
9/8/2018· The Young’s modulus (E), or the modulus of elasticity, of a material determines the level of applied force required before it bends or breaks. It describes the constant ratio of tensile stress ( σ ) to tensile strain ( ε ) within the elastic limits of materials for both tension and compressive forces.
Young’s Modulus, Residual Stress, and Crystal …
14/4/2015· Initial or residual stress plays an important role in nanoelectronics. Valley degeneracy in silicon nanowires (SiNWs) is partially lifted due to built-in stresses, and consequently, electron–phonon stering rate is reduced and device mobility and performance are improved. In this study we use a nonlinear model describing the force-deflection relationship to extract the Young’s modulus
