Electrons confined inside NANO-PYRAMID
Quantum
dots are nanostructures of semiconducting materials that behave a lot like
single atoms and are very easy to produce. Given their special properties,
researchers see huge potential for quantum dots in technological applications.
Before this can happen, however, we need a better understanding of how the
electrons "trapped" inside them behave. Dresden physicists have
recently observed how electrons in individual quantum dots absorb energy and
emit it again as light.
Quantum
dots look like tiny pyramids. Inside each of these nano-pyramids are always
only one or two electrons that essentially "feel" the constricting
walls around them and are therefore tightly constrained in their movability. TU
Dresden and the Leibniz Institute for solid State and Materials Research Dresden
(IFW) have now studied the special energy states of the electrons trapped
inside individual quantum dots.
Conclusion:
I
chose this article because it thought it would be interesting to learn about quantum dots are. What
grabbed my attention was the picture of, what I though was, a light ray. Well, I was so interested in it
that I decided to read the article. I found it while looking at the Science Daily website and was just skimming through the articles when I came to this one that
seamed interesting and was screaming, READ ME, READ ME, READ ME!!!!!!!!!
