Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications.”

INTRODUCTION TO NANOTECHNOLOGY

“Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.”

Moore’s Law describes a trend of technology. It states that the number of transistors that can be put on a single chip will double every two years.

A schematic diagram of the NIST nanowire transistor.

Instead of making transistor components and assembling them on a board, nanoscale transistors are grown together on a silicon wafer. They look much different from the traditional transistors.

Nano Transistor

The human brain has about 100 billion neurons.

Each neuron has thousands of synapses.

The newest processors have only two billion transistors.

Because of nanotechnology, the speed of computers has increased while the price of computing has decreased.

This is a 2 gigabyte hard drive. It weighs about 70 pounds. It was first used in the 1980s. Its cost at that time ranged from

$80,000 to $140,000.

2 GB in 1980s $80,000

2 GB in 1990s $200

2 GB in 2010 $5

Current research shows that by using nanotechnology, 1000 GB of memory can fit on the head of this pin. 1000 GB is 1 Terabyte.

Nanotubes are small enough that they cannot be seen, so they can be great conductors to be used as transparent contacts.

These layers contain transparent electrodes

Carbon nanotubes on a glass or plastic sheet allow manufacturers to make clear conductive panels for displays that are extremely thin.
