Phonon Spectroscopy and Low-Dimensional Electron Systems
… give unique information about the properties of low-dimensional electron systems, but in order to interpret the experiments and to understand the underlying physics, a comparison with theoretical models is absolutely necessary. A central point of this work is therefore a universal theoretical …

Theoretical study of interacting low dimensional electron systems
… problem: the Hubbard model on one- and two-dimensional lattices. The technique employed is the small-cluster method wherein the full many-body Hamiltonian for finite clusters with periodic boundary conditions (PBC's) is solved exactly. We first apply this technique to an extended …

Low-dimensional electron systems fabricated with an atomic force microscope
… there has been intensive research into electron transport in low dimensional systems, especially those fabricated in semiconductor material. This research has added to our understanding of electrical transport properties outside of the macroscopic regime, and allowed exploration of …

Theory and modeling of field electron emission from low-dimensional electron systems
… have succeeded in fabricating nanoscale field electron emitters in a variety of geometries and materials for use as electron sources in vacuum nanoelectronic devices, theory and modeling of field electron emission have not kept pace. Treatments of field emission which address individual …

Interaction and Mixing Effects in Two and One Dimensional Hole Systems
… describes electrical measurements performed on low dimensional p- type devices, fabricated from GaAs/AlGaAs heterostructures. The Coulomb interaction between holes is similar to that between electrons. However, the kinetic energy is suppressed, which makes interaction effects particularly …
