Symmetry Effect

Effects of confinement potential hω0 on two- and four-electron quantum dots (QDs) subjected to an external magnetic field B are theoretically investigated. The energy spectra of low-lying states of the QDs as a function of B are obtained. The (L0, S0) phase diagrams are presented, indicating how the ground-state transitions of the QDs vary with B and hω0, where L0 denotes the total angular momentum and S0 the total spin of the ground states. Arising from symmetry effect, L0 and S0 are matched with each other in a special way. Density functions are calculated, and information on electronic configurations is extracted from them. The ground states are found to have a regular-polygon configuration.

A lithium quantum dot (QD) with a charged impurity is studied, where the charged impurity is located on the z-axis at a distance d from the lithium QD plane (the x–y plane). Using the method of few-body physics, the energy spectra of the low-lying states of the QD are obtained as a function of d. It is found that the energy spectra depend strongly on both the position and charge of the impurity. Furthermore, the impurity affects the electronic configurations of the QD, i.e. the spatial distribution of the electrons of the QD. Our calculations indicate that the change of d induces transitions in the ground states of the QD, which can be explained by dynamics and symmetry.

Heterogeneous molecular catalysts based on transition metal complexes have received increasing attention for their potential application in electrochemical energy conversion. The structural tuning of first and second coordination spheres of complexes provides versatile strategies for optimizing the activities of heterogeneous molecular catalysts and appropriate model systems for investigating the mechanism of structural variations on the activity. In this review, we first discuss the variation of first spheres by tuning ligated atoms; afterward, the structural tuning of second spheres by appending adjacent metal centers, pendant groups, electron withdrawing/donating, and conjugating moieties on the ligands is elaborated. Overall, these structural tuning resulted in different impacts on the geometric and electronic configurations of complexes, and the improved activity is achieved through tuning the stability of chemisorbed reactants and the redox behaviors of immobilized complexes.

Electronic Configurations

The metallic and semiconducting character of a large family of organic materials based on the electron donor molecule tetrathiafulvalene (TTF) is rooted in the partial oxidation (charge transfer or mixed valency) of TTF derivatives leading to partially filled molecular orbital-based electronic bands. The intrinsic structure of such complexes, with segregated donor and acceptor molecular chains or planes, leads to anisotropic electronic properties (quasi one-dimensional or two-dimensional) and morphology (needle-like or platelet-like crystals). Recently, such materials have been synthesized as nanoparticles by intentionally frustrating the intrinsic anisotropic growth. X-ray photoemission spectroscopy (XPS) has emerged as a valuable technique to characterize the transfer of charge due to its ability to discriminate the different chemical environments or electronic configurations manifested by chemical shifts of core level lines in high-resolution spectra. Since the photoemission process is inherently fast (well below the femtosecond time scale), dynamic processes can be efficiently explored. We determine here the fingerprint of partial oxidation on the photoemission lines of nanoparticles of selected TTF-based conductors.
