Fig. 1. Fixed-fixed beams fabricated from amorphous silicon carbide films deposited by PECVD. The beam is buckled due to presence of compressively residual stress in the thin film. | Fig. 2. An array of such buckled beams of varying dimensions. |

Fig. 3. Non-dimensional frequency (first four modes) vs. Non-dimensional axial load parameter plot for compressive residual stress carrying buckled PECVD-SiCx beams. Solid-lines and points show the analytical prediction and measured natural frequencies respectively and the dashed lines show the sensitivity of frequency to residual stress. |
