Why Nano for Electronics New designed materials offer new and
unique properties
Slide 3
Enables the development and cost efficient production of
state-of-the-art components operate faster has higher sensitivity
consume less power can be packed at much higher densities It can
become stronger, conduct heat better, and show extraordinary
electrical properties What Properties?
Slide 4
Example: at the nanoscale, the resistance dependence of a
material on an external magnetic field is significantly amplified,
which has led to the fabrication of hard disks with a data storage
density in the gigabyte and terabyte ranges. Nanotechnology has
also enabled the development of sensors suitable for measurements
at the molecular level with an unprecedented sensitivity and
response time, mainly due to their high surface to volume
ratio.
