         ABOUT QUANTUM DOTS

 

7 Atoms high and 10 - 20 atoms in diameter

            (height of a strand of DNA)

 

Man-made quantum mechanical systems

 

In the quantum region the traditional rules

of  physics change.

     

We take advantage of these changes to

create our breakthrough devices
