Abstract: Studies of the relief formed on the surface of nanostructured nickel with nonequilibrium grain boundaries formed upon ion-beam sputtering are presented. It has been shown that the relief on the nano-structured nickel surface differs substantially from the relief formed on the surface of the coarse-grained nickel with equilibrium grain boundaries. In particular, a multipeak relief with submicron dimensionality of the peaks forms on the surface of nanostructured nickel under certain conditions. This relief is advantageous for the field electron emission. For the sample with multipeak relief, a CVC of field electron emission is measured.
