Momentum Space Calculations of Nano Scaled Semiconductor Materials — •Marcel Dohrmann, Christian Strelow, and Alf Mews — Institute of Physical Chemistry, University Hamburg, Grindelalle 117, 20146 Hamburg, Germany

Excitons energy calculations are done by solving Schrödinger's equations of kinetic terms, including the effective mass of electrons and holes, and potential terms. In position space, three-dimensional self-consistent calculations with hole and electron functions are used to understand different nano sized semiconductors like CdSe/CdS dot-rods.[1] Using fourier transformations the kinetic and potential Hamiltonians in position space can be adapted to momentum space. A potential landscape in momentum space is an approach to calculate energy levels of electrons and holes in different composites. We see forward to study interaction between heavy and light holes in semiconductor nanomaterials.
