Optical Tunneling to Improve Light Extraction in Quantum Dot and Perovskite Light-Emitting Diodes
IEEE Photonics Journal, 2020 An effective strategy based on optical tunneling is developed to significantly improve the efficiency of quantum dots light-emitting diodes (QLEDs) and perovskite light-emitting diodes (PeLEDs).

Quantum computation with quantum dots [PDF]
Physical Review A, 1998 We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are effected by the gating of the tunneling barrier between neighboring dots.

Piezomagnetic Quantum Dots [PDF]
Physical Review Letters, 2008 We study the influence of deformations on magnetic ordering in quantum dots doped with magnetic impurities. The reduction of symmetry and the associated deformation from circular to elliptical quantum confinement lead to the formation of piezomagnetic quantum dots.

AIP Advances, 2020 Although structural phase transitions in single-crystal hybrid methyl-ammonium (MA) lead halide perovskites (MAPbX3, X = Cl, Br, I) as a function of temperature are common phenomena, they have never been observed in the corresponding nanocrystals.

Spectroelectrochemistry of Quantum Dots [PDF]
Israel Journal of Chemistry, 2019 AbstractSpectroelectrochemistry (SEC) is a set of techniques with many advantages in the study and characterization of materials. Although SEC has not yet been widely used to study quantum dots (QDs), the information extracted from SEC experiments about these nanostructures is very useful.
