Abstract : The creation of miniaturized mechanical structures and devices calls for an understanding of the mechanical properties of the semiconductor and metallic materials used at these small length scales. Investigation of different types of loading, such as compression or bending, requires the development of appropriate miniaturized instrumentation and integration into different micro-analysis instruments (SEM, optical probes etc.) allowing for in-situ microstructure analysis. The talk will illustrate different materials case studies using in-situ nanomechanical testing: sample size and temperature dependent brittle to ductile transitions in semiconductors, shear band formation in amorphous metals, displacement bursts and thinness effect in crystalline metals.
