Properties at the nanoscale Magnetic,mechanical,and chemical behaviour Top-down approaches have Microelectronics Nanotechnology been developed for building top-down approach,build in place bottom-up approach,self-assembly structures at the scale of the 01-10m 1-100nm micrometre (u m).Bottom- up techniques have also been developed for assembling small groups of atoms or molecules at the scale of nanometres(nm). The remaining task is to combine these approaches in order to create extended structures at the nanoscale Company Logo Company Logo Properties at the nanoscale Magnetic, mechanical, and Magnetic, mechanical, and Magnetic, mechanical, and chemical behaviour chemical behaviour chemical behaviour Top-down approaches have been developed for building structures at the scale of the micrometre ( μm).
