Electronic and optical properties of single excitons and biexcitons in type-II quantum dot nanocrystals
(AIP Publishing, 2014)
In this study, a detailed investigation of the electronic and optical properties (i.e., binding energies, absorption wavelength, overlap of the electron-hole wave functions, recombination oscillator strength, etc.) of an ...
Optical Properties in a ZnS/CdS/ZnS Core/Shell/Shell Spherical Quantum Dot: Electric and Magnetic Field and Donor Impurity Effects
(MDPI, 2023)
A theoretical analysis of optical properties in a ZnS/CdS/ZnS core/shell/shell spherical quantum dot was carried out within the effective mass approximation. The corresponding Schrödinger equation was solved using the ...

Double Quantum Ring under an Intense Nonresonant Laser Field: Zeeman and Spin-Orbit Interaction Effects
(MDPI, 2023)
We theoretically investigate the properties of an electron energy spectrum in a double
GaAs-Al0.3Ga0.7As quantum ring by using the effective mass and adiabatic approximations, together
with a realistic description of the ...
Elliptical Quantum Rings with Variable Heights and under Spin-Orbit Interactions
(MDPI, 2023)
We investigate the electronic properties of a semiconductor quantum ring with an elliptical
shape and non-uniform height, allowing for distributed quantum-dot-like bulges along its perimeter.
The adiabatic approximation ...
Antibacterial type-II InP/ZnO quantum dots via multimodal reactive oxygen species
(ELSEVIER SCIENCE SA, 2024)
The emergence of multidrug-resistant bacteria as a global health threat has necessitated the exploration of alternative treatments to combat bacterial infections. Among these, photocatalytic nanomaterials such as quantum ...
Cadmium-Free and Efficient Type-II InP/ZnO/ZnS Quantum Dots and Their Application for LEDs
(AMER CHEMICAL SOC1155 16TH ST, NW, WASHINGTON, DC 20036, 2021)
It is a generally accepted perspective that type-II nanocrystal quantum dots (QDs) have low quantum yield due to the separation of the electron and hole wavefunctions. Recently, high quantum yield levels were reported for ...
