A Technique for Estimation of Residual Stress and Young’s Modulus of Compressively Stressed Thin Films Using Microfabried Beams Abstract: Predictive design of MEMS devices and their performance evaluation require post-fabriion measurement of essential material properties, such as Young’s modulus and residual stress, as these are usually affected by fabriion process conditions.
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
Silicon Carbide Balls: The ability of Silicon Carbide to withstand very high temperatures without breaking or distorting is used in the manufacture of ceramic brake discs for sports cars. It is also used in bulletproof vests as an armor material and as a seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal.

Hardness (//), Young''s modulus (E), and Poisson''s ratio (v) of the studied silicon carbide thin films were determined. It is shown that for hydrogenated fl-Si x Ci_ x : H PECVD
The thermal coefficient of Young''s modulus, 1/E · δE/δT was measured to be -52.6 ± 3.45 ppm/K for silicon and -39.8 ± 5.99 ppm/K for 3C silicon carbide, agreeing well with theoretical predictions, and also with experimental values that have been previously
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
Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).-SiC (rhoohedral unit cell).
