Description

This item was taken from the IEEE Conference ' Work function measurement of Nd-oxide/W(100) surface by using of photoemission electron microscope ' A cathode material of a low work function is needed to achieve a high performance electron source. We measured the work function of W(100) surface modified with Nd2O3 by using of photoemission electron microscope. The work function of Nd-oxide/W(100) surface is measured to be 2.5eV.
