The reduction in size of otherwise well characterized materials can signficantly modify their optical and electronic properties. This is true for the piezoresistance (the mechanical stress induced variation of the electrical resistivity) in semiconductor materials like silicon.
Mechanical stress is widely used to improve the performance of commercial, microelectronic semiconductor devices. As device sizes shrink to physical lengths scales coresponding to electrostatic screening lengths, the effect of mechanical on electronic properties can be radically different. In this activity we study these novel physical phenomena.
