Energy-resolved momentum densities for the valence band of a nanoscale Si single crystal
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 momentum spectroscopy (EMS) for a self-supporting Si membrane with a thickness of approximately 7 nm. We compare our experimental results with ab initio calculations for bulk crystalline silicon performed within the linear muffin tin orbital...[Show more]
