Colloidal semiconductor nanocrystals have emerged as promising materials for next-generation light-emitting diodes (LEDs) owing to their solution processability, tunable emission wavelengths, narrow emission linewidths, and high photoluminescence quantum yields. Among them, anisotropic nanocrystals, including one-dimensional nanorods (NRs) and two-dimensional nanoplatelets (NPLs), offer additional opportunities for controlling transition dipole moment orientation and light out-coupling efficiency. These unique structural characteristics have enabled significant advances in LED performance beyond those achievable with conventional spherical quantum dots. This review summarizes recent progress in anisotropic semiconductor nanocrystals for light-emitting applications. We first discuss the synthesis and structural modulation of NRs and NPLs, including size and morphology control, heterostructure engineering, and doping strategies. We then review the fundamental operating principles of anisotropic nanocrystal-based LEDs, emphasizing the relationships among nanocrystal structure, carrier dynamics, dipole orientation, and device performance. Recent advances in CdSe-based, perovskite-based, and wide-bandgap semiconductor anisotropic nanocrystal LEDs are highlighted, with particular focuses on heterostructure design, charge-balance regulation, and light-management strategies. In addition, directed assembly approaches for constructing oriented nanocrystal films and their impact on light out-coupling efficiency are discussed. Finally, the remaining challenges are outlined. We believe that continued advances in materials design, device architecture optimization and assembly engineering will further accelerate the development of anisotropic nanocrystal LEDs for high-efficiency next-generation display and solid-state lighting technologies.

Zubov A., Zubov A., Малявко, Я. et al., Computer Physics Communications 2025 Vol. 317 Article 109860

The concept of representative volume (REV, or RVE in material sciences) is the cornerstone of continuum scale models – one needs to get the volume big enough so that it could be represented with an averaged value (scalar, vector or tensorial, etc.). While REV should be established in all larger scale simulations, this is rarely ...

From frozen Coulomb decoherence to thermalization: Classical and quantum density-matrix routes to Balescu–Lenard and Landau kinetics

Budkov Y., Annals of Physics 2026 Vol. 495 No. 3 Article 170796

We study the density-matrix kinetics of a charged test particle in two types of Coulomb environment. For a prescribed Gaussian potential, averaging the random-unitary dynamics leads to a Born–Novikov memory equation; Novikov’s identity is exact, but its closure requires a second-order approximation. An equilibrium quantum bath instead yields a Born–Redfield equation with ordered correlators and ...

D.V. Khomitsky, Lavrukhina E. A., Krasavin D. P. et al., Physical Review B: Condensed Matter and Materials Physics 2026 Vol. 114 No. 22 Article 225414

We study coherent electric manipulation of magnetic field induced localized states at a double kink of a helical edge in a HgTe/CdHgTe quantum well. An in-plane magnetic field opens a gap in the one-dimensional (1D) edge spectrum, while changes in the edge orientation generate localized in-gap states at the kinks. We show that, for suitable ...
