Si nanocrystals have been extensively studied because of their novel properties and their
potential applications in electronic, optoelectronic, photovoltaic, thermoelectric and …

Developing practical approaches to effectively reduce the amount of deep defect levels in
semiconductors is critical for their use in electronic and optoelectronic devices, but this still …

Copper-doped and copper-based colloidal semiconductor nanocrystals have attracted
broad attention as phosphors in many contexts, but fundamental aspects of their electronic …

Solving the Kohn–Sham equation, which arises in density functional theory, is a standard
procedure to determine the electronic structure of atoms, molecules, and condensed matter …

We develop a method in which the electronic densities of small fragments determined by
Kohn-Sham density functional theory (DFT) are embedded using stochastic DFT to form the …

In this review, we discuss several fundamental processes taking place in semiconductor
nanocrystals (quantum dots (QDs)) when their electron subsystem interacts with …

Colored nitrogen-vacancy (NV) centers in nanosize diamonds (d∼ 5 nm) are promising
probe materials because their optical transitions are sensitive to mechanical, vibrational …

The interplay of oppositely charged substitutions in the structure of hydroxyapatite (HAp)
nanopowders is investigated on the atomic level by pulsed electron paramagnetic …

Diamonds approaching the nanoscale have the potential for use as probe materials as their
optical properties can be sensitive to optical/electric fields, mechanical stress/pressure, and …

Free-standing ZnO nanocrystals simultaneously doped with Fe and Cu with varying Fe/Cu
compositions have been synthesized using colloidal methods with a mean size of∼ 7.7 nm …
