Delgado G.E., Mora A.J., Marcano G., Rincon C.: "Crystal structure refinement of the semiconducting compound
[Cu.sub.2]Sn[S.sub.3] from X-ray powder diffraction data".
Choi and postdoctoral researcher Tae Woo Kim found that if they heated an electrode made of the semiconducting compound
bismuth vanadate to 350 degrees Celsius while flowing nitrogen gas over it, some of the nitrogen was incorporated into the compound.
Once they'd mastered the technique, the researchers used it to create a wee transistor from a nanocrystal of cadmium selenide, a semiconducting compound
. A year later, the team used the same method to make another transistor from the 60-carbon-atom, soccer ball-shape molecule known as a buckyball (SN: 7/13/02, p.
