Solar cells and computer chips need silicon layers that are as perfect as possible. Every imperfection in the crystalline structure increases the risk of reduced efficiency or defective switching ...

Lewis structures, also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in ...

The atomic silicon quantum dot (ASiQD) described here fits within ultra low power schemes for beyond CMOS electronics based upon quantum dots that have been refined over the past 2 decades. The well ...

New silicon structure opens the gate to quantum computers ... conventional computers work by manipulating the electron's negative charge. ... in a well-like structure called a double quantum dot. ...

Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, a group of researchers is hoping its work with quantum dot solids -- crystals made out of ...

Figure 1- Electron microscope image of a three-dimensional diamond structure in silicon (encircled), consisting of identical pores in an orthogonal pattern that cross each other at an angle of 90º.

Interestingly such a diamond structure acts as a semiconductor for light, a building block for a future optical computer that switches light instead of electric current. Figure 1: electron microscope ...

Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids -- crystals made out of ...
