Latest Field electron emission Stories

2011-11-21 12:17:58

Field emission devices, which produce a steady stream of electrons, have a host of consumer, industrial, and research applications. Recent designs based on nanotubes and other nanomaterials embedded in plastics show initial promise, but have a number of drawbacks that hinder their wide-scale application. The embedded nanotubes, which serve as the source for the electrons, also enable the normally inert plastic to conduct electricity. This has the desired effect of producing a versatile and...

New video showing the atom-by-atom growth of carbon nanotubes reveals they rotate as they grow, much like the halting motion of a mechanical clock's second hand. FEM video from Universit© Lyon1/CNRS shows the rotation of the nanotube during growth. The observation helps confirm a new rotational theory of carbon nanotube growth offered by Rice researchers in February.Published online this month by researchers at France's Universit© Lyon1/CNRS and Houston's Rice University, the...
