1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

2. Wannier functions from Bloch orbitals in solids
Kandidat-uppsats, MaterialteoriSammanfattning : Wannierfunctions are a superposition of the Blochorbitals in a Brillouin zone belonging to a manifold of energy bands. These Wannier functions have several uses regarding the analysis of the crystal on a local level. LÄS MER
