Researchers discover a new theory that paves the way for the design of better graphene electronics and energy converters. When a metal is heated to a sufficiently high temperature, electrons can be ...

(Nanowerk Spotlight) Heat energy can be converted into electricity with very high efficiency through a temperature-induced electron flow process known as thermionic emission. The basic operating ...

THE object of this note is to describe a case in which electrons were observed to arrive at the most negative electrode in a thermionic valve with sufficient energy to cause secondary emission.

When a metal is heated to a sufficiently high temperature, electrons can be ejected out from the surface in a process known as the thermionic emission, a process that is similar to the evaporation of ...
