(PhysOrg.com) -- When single walled carbon nanotubes (SWCNTs) are made, they come out in both metallic and semiconducting material form. Unfortunately, different applications require one or the other of these materials, but ...
Developing solar energy that is low-cost, lightweight, and energy efficient has proven to be one of the greatest challenges the science world faces today. Although current plastic solar cells are low in cost and easy to produce, ...

(PhysOrg.com) -- A group of researchers working in Japan has devised a means of creating dual segmented nanotubes where each segment has separate and distinct semiconducting properties. The team describes how they were able ...
Recent breakthroughs have enabled scientists from the Northwestern University's Center for Quantum Devices to build cameras that can see more than one optical waveband or "color" in the dark. The semiconducting material used ...
