Special Issue Information

Dear Colleagues,

Recently, the progress has been impressive in the synthesis of various 0D, 1D, and 2D nanostructures based on dielectric, semiconductor, and metallic materials, as well as based on their composites, including metamaterials. Such nanostructures are successfully used in electronics, photonics, sensing, biology, and medicine. Also of interest are carbon nanostructures (based on graphene or carbon dots), plasmon nanostructures, and the use of perovskites as key materials in nanostructures. The rapid development of technology for creating new nanostructures requires the research community to comprehensively analyze their electronic and optical properties. This analysis will provide a deeper understanding of the physics of low-dimensional systems and will broaden the scope of nanostructure applications.

This Special Issue will highlight the latest advances in the study of electronic and optical properties of various types of nanostructures. We invite researchers to submit their original research articles, letters, and reviews on fundamental and applied studies of nanostructures.

This paper presents the first general theory of electronic band structure and intersubband transitions in three-layer semiconductor nanoplatelets. We find a dispersion relation and wave functions of the confined electrons and use them to analyze the band structure of core/shell nanoplatelets with equal thicknesses of the shell layers. It is shown that the energies of electrons localized inside the shell layers can be degenerate for certain electron wave vectors and certain core and shell thicknesses. We also show that the energies of intersubband transitions can be nonmonotonic functions of the core and shell thicknesses, exhibiting pronounced local minima and maxima which can be observed in the infrared absorption spectra. Our results will prove useful for the design of photonic devices based on multilayered semiconductor nanoplatelets operating at infrared frequencies. Full article

Ligand-Assisted Formation of Graphene/Quantum Dot Monolayers with Improved Morphological and Electrical Properties
Nanomaterials 2020, 10(4), 723; https://doi.org/10.3390/nano10040723 - 11 Apr 2020
Abstract
Hybrid nanomaterials based on graphene and PbS quantum dots (QDs) have demonstrated promising applications in optoelectronics. However, the formation of high-quality large-area hybrid films remains technologically challenging.

Hybrid nanomaterials based on graphene and PbS quantum dots (QDs) have demonstrated promising applications in optoelectronics. However, the formation of high-quality large-area hybrid films remains technologically challenging. Here, we demonstrate that ligand-assisted self-organization of covalently bonded PbS QDs and reduced graphene oxide (rGO) can be utilized for the formation of highly uniform monolayers. After the post-deposition ligand exchange, these films demonstrated high conductivity and photoresponse. The obtained films demonstrate a remarkable improvement in morphology and charge transport compared to those obtained by the spin-coating method. It is expected that these materials might find a range of applications in photovoltaics and optoelectronics. Full article

Photoelectrical and photoluminescent properties of multilayer graphene (MLG)–quantum dots (QD) hybrid structures have been studied. It has been shown that the average rate of transfer from QDs to the MLG can be estimated via photoinduced processes on the QDs’ surfaces. A monolayer of CdSe QDs can double the photoresponse amplitude of multilayer graphene, without influencing its characteristic photoresponse time. It has been found that efficient charge or energy transfer from QDs to MLG with a rate higher than 3 × 108 s−1 strongly inhibits photoinduced processes on the QD surfaces and provides photostability for QD-based structures.
