Electronic structure as a research area focuses on the quantum-mechanical description of electrons in atoms, molecules, solids, and nanostructures, and on how this governs their structural, spectroscopic, and transport properties. It encompasses the development and application of theoretical methods such as density functional theory, wavefunction-based quantum chemistry, many-body perturbation theory, and quantum Monte Carlo to compute energies, charge densities, band structures, and excited states. The field underpins predictive materials design, catalysis, electronic and photonic device engineering, and strongly correlated systems research by linking microscopic electron behavior to macroscopic observables and emergent phenomena.
In a recent study, a research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences achieved higher thermoelectric performance of n-type lead telluride (PbTe) by adjusting the band structure ...
