We report the fabrication of a 10 nm thick, self-supporting, single-crystal silicon membrane. The fabrication process can be broken up into four major stages. First, a buried SiO2 layer was formed by implantation of oxygen at a depth of 200 nm into a

We have measured the energy- and momentum-resolved band structure, and ground state of occupation of the bands, for a crystalline silicon sample along the 100 and 110 directions. Band structures were determined directly by the technique of electron m

Electron momentum spectroscopy (EMS) has been used to measure the valence band electronic structure of thin magnesium and magnesium oxide films. The band structures have also been calculated within the linear muffin-tin orbital (LMTO) approximation.

The electronic excitation spectra at arbitrary momentum values can be determined in principle by (e,2e) spectroscopy. These experiments are performed using high energy electrons (1 keV up to 20 keV) meaning that refraction of electrons at the surface

Electron-momentum spectroscopy based on the $(e,2e)$ reaction has been used to observe the energy-momentum density of valence electrons in the [110] direction for an ultrathin, free-standing film of crystalline silicon. An asymmetric scattering geome

We present measurements of the spectral momentum density of aluminum films and compare these results with two different theories. One theory is a standard band structure calculation, taking into account the lattice potential; the other theory neglect

We have measured the energy-momentum density of amorphous silicon dioxide using an $(e,2e)$ spectrometer with 20.8 keV incident, 19.6 keV scattered, and 1.2-keV ejected electron energies. The amorphous ${\mathrm{SiO}}_{2}$ sample was prepared by oxid

We describe in detail the procedures used for the preparation of ultrathin (∼10 nm) free-standing membranes for (e,2e) spectroscopy. Such a thin target is needed to minimize electron multiple scattering before and after an (e,2e) event. The develop

The energy-resolved electron-momentum density of fullerene has been measured. Clear differences are found from the energy-momentum densities of either diamond or graphite. The energy-momentum density of fullerene can be described as being composed of
