Cool nanotech image — cadmium sulfide semiconducting laser

This image is part of the series linked in the previous post on the laser turning 50, but it deserves highlighting as a very cool nanotechnology image.

Researchers at the University of California, Berkeley, have created the smallest semiconducting laser, which could eventually be used for optical computing. A cadmium sulfide wire 50 nanometers in diameter generates visible light and holds it in a five-nanometer space.

  1. What exactly do you mean by ” … holds it in a five-nanometer space.”?

  2. I am a middle school teacher in NC and came across your site while researching some information about the periodic table for my chemistry class this year. I just wanted to thank you for the great information.

    We would love it if you could write a few articles for us, but I understand if your busy so a link to some of the current articles would be very helpful as well to help us spread trusted resources to other teachers. I have included a link to our page about cadmium and its toxic effects in case you would like to help us out by linking to it, tweeting it, or adding it to your Facebook profile.

    Thanks and keep the great resources coming
