Semester Project Advanced NEMS Group CHARACTERIZATION OF MECHANICAL PROPERTIES OF MICRO/NANO BEAMS

چکیده
In this project, characterization of a series of previously fabricated Aluminium clamped-clamped micro beams and cantilevers by electrical measurements in order to investigate the effects of scaling down on mechanical properties of micro/nano structures is presented. The Young’s modulus that depends on the thickness of the microstructure, residual stress and surface properties as opposed to a constant Young’s modulus in macro scale theories was investigated. Due to insufficient sample space and high stresses during fabrication, a correlation was not obtained. KeywordsAluminium beams, Coupled Stress theory, Residual Stress theory, Surface Elasticity theory, Combined stress model, electrical characterization.

Study of Laminated Composite MEMS and NEMS Performance in Nano Metric Operations
Precision of nano-metric operations is an important issue in nano-engineering studies. Several operative parameters might affect the quality of results. The parameters of the nano world are significant but not entirely controllable. However, the geometrical and mechanical properties of micro cantilevers are completely controllable. So, controlling the sensitivity of resulting image through t la...

Silicothermic production and characterization of FeSiNi/SiO2 Magnetic nanocompsite via mechanical alloying
In recent years, a lot of research has been done in the field of producing soft magnetic nano composites by means of mechanical alloying. These materials indicate more electrical resistance and permeability in comparison with soft magnetic composites (SMCs). In this research, reduction of silicothermal mixed powder (Nickel-oxide, Silicon and Iron) was carried out by mechanical alloying to form ...
