Modern semiconductor technology is inexorably approaching the threshold of miniaturization and, as a result, its efficiency against the background of rapidly growing needs for high-performance processing systems, and the storage and safe transfer of large amounts of data. This necessitates the transition to fundamentally new architectures of computing and telecommunication platforms, primarily hybrid, based on the integration of further options for the development of a traditional and promising electronic component base with the principles of quantum electronics and photonics. Of particular note is the relevance of the creation of solid-state schemes for the implementation of such platforms, coupled with the current and/or predictable capabilities of production processes and research tools in the framework of conditionally planar technology.
Building such platforms is possible on the basis of such promising functional elements as highly efficient sources of single and entangled photons (quantum communication and cryptography), quantum registers (quantum computing and memory/quantum computing), structural units (blocks) of cellular automata, functional and structural blocks of hybrid integral schemes (for example, microdisk lasers on whispering gallery mods), etc. This, in turn, requires the development of new methods and approaches in the field of designing functional elements of nano- and optoelectronics, conducting research in the field of creating new functional materials based on various types of nanostructures, etc.
This Special Issue, “Electronic Materials and Devices”, will be a collection of full papers, short communications and review papers focusing on recent progress in the field of semiconductor nanostructures, the technology of their production and promising nano- and optoelecronic elements and devices based on them.

1.5 μm AlGaInAs quantum well (QW) lasers have great potential in the application fields of optical communications, eye-safity lidars and three-dimensional imaging, owing to the advantages of low temperature sensitivity of threshold current and good gain performance. Numerous experimental evidence indicated that carriers capture-escape processes affect the resonant frequency and modulation response performance of QW lasers. However, the mechanism of carrier dynamic in AlGaInAs QW structure is still ambigous for complicated artificial multilayer. In this paper, the carrier dynamics of AlGaInAs QW were investigated by temperature-dependent time-resolved photoluminescence (TRPL) in the temperature range of 14-300 K. A non-monotone evolution in carrier escape process was observed at low temperature. The escape rate of carriers in AlGaInAs QW increase with the decrease of temperature, and it's quite different from that in bulk semiconductor. Two optical transitions were demonstrated to have major impact on the PL emission of AlGaInAs QW in the low-temperature range. The phenomena above were associated with the lattice strain fluctuation between adjacent layers. The study of carrier dynamic process has a significant influence on the optical properties and localization of carriers in the AlGaInAs QWs.
