โœฆ Synopsis


Upon bombardmen~ with very slow electrons (Vp = circa 10 volts) the electropositive elements (barium) have a higher secondary electron emission than metals such as silver. The coefficient of elastic reflection of barium is less than that of silver. Compounds of the electropositive elements have a high capacity for secondary emission and for reflection.

The secondary electron emission (SEE) yield of heterostructures of zinc oxide (ZnO) nanoneedles coaxially coated with aluminum nitride (AlN) or gallium nitride (GaN) has been studied using ion and X-ray beams. This paper describes experiments performed with ions (2 MeV protons and 3.6 MeV/nucleon ca
