  1. 36. Electronic Structure of Transition Metal Complexes in Silicon

    Författare :Per Tidlund; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uniaxial stress; FTIR; Zeeman spectroscopy; deep levels; phonon-assisted Fano resonances; Physics; Fysik; Au; Fysicumarkivet A:1998:Tidlund; PtLi; AuLi; Pt; Transition Metals; Silicon;

    Sammanfattning : This thesis consists of experimental studies of the electronic of electronic structure of the transition metals Au and Pt, and the transition metal complexes, FeIn, PtLi, and AuLi in silicon. Fourier transform infrared spectroscopy, photoconductivity, uniaxial stress- and Zeeman spectroscopy are employed. LÄS MER

    Författare :Francesco Aquilante; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; orbital localization; electron correlation; analytic gradients; Cholesky decomposition; density fitting; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Recent years have witnessed a growing interest of the scientific community for the use of ab initio and density functional theory methods in theoretical studies of molecules containing many atoms. However, the `scaling wall' of some of the most accurate of such methods is often an obstacle for their applicability to systems of real-life interest, e. LÄS MER
