Two Dimensional Transisters

From Voice of America News:
Just when it looked like electronic components could not get smaller, scientists in the United States announced that they have created the first transistor that - for all practical purposes - has only two dimensions. Such transistors could someday be used for building flexible high-resolution displays that need very little energy.

An atom is only about one-tenth of a billionth of a meter wide, so a layer of any material that thin may be considered two-dimensional.

Two groups of scientists - at Argonne National Laboratory outside Chicago and at the University of California - report they have successfully built transistors only a few atoms thick, with materials that have better electronic properties than silicon.
The primary advantage are flexibility and fast switching times.
