Abstract To estimate the field-emission current density of a Ge/Si heterosystem, 20-nm germanium/silicon (100) samples were grown by molecular beam epitaxy. The surface of one sample was covered with a layer of antimony, which was removed in vacuum prior to the samples being measured. A second sample of Ge/Si was exposed to room air in the absence of antimony. The current–voltage characteristics of both samples obtained by scanning tunneling microscopy (STM) were discovered to be in agreement with classical Fowler–Nordheim theory. The density of emission current from Ge nanocrystal exceeds the density of emission current from the wetting layer of Ge/Si. The density of emission current of pure Ge nanocrystal is less than the density of emission current of Ge nanocrystal with adsorption layers.

Abstract The technological prospects for the creation of a system of microfocus X-ray tubes with the use of silicon field emission of nanocathodes have been discussed. A numerical analysis of the field-emission current from a nanoscale semiconductor cathode regulated by voltage on a grid electrode has been carried out on the basis of which a scheme for controlling the elements of the matrix of field-emission cathode assemblies has been proposed. The current–voltage characteristics of silicon field emission nanocathodes have been measured. They are in good agreement with the theoretical estimates of the field-emission current. A full technological cycle of the development of elements of microfocus X-ray tubes (a set of field-emission cathode assemblies and a set of anode assemblies) has been performed. The results can be used to create systems of microfocus X-ray tubes for nanolithographic equipment of a new generation.
