Project summary

Low-dimensional systems are of special interest for the physics researchers in view of new possibilities, such as fabrication (by means of a novel hetero-epitaxial-growth technology) of artificial semiconducting nanostructures with the desirable energy-level configuration. Such structures are the most appropriate elemental basis for micro- and opto-electronics, as well as for future X-ray optics.

The investigation of the low-dimensional state of matter also provides inviting prospects outside micro- and opto-electronics fields. Recently, it has become apparent that this state of the matter is a model form of a special substance that fills in the universe volumes and constitutes, in particular, neutron stars. Thus, any study of low-dimensional structures is of the current interest not only for future applications but also for the understanding of fundamental properties of the matter.

Unfortunately, a direct study of low-dimensional systems is not always possible. Thereby, the use of experimental sophisticated-simulation methods might be decisive here. For example, the application of magnetic and/or electric fields can reduce the behavior dimensionality of a charged particle.

This project is intended to experimentally simulate one- and two-dimensional behavior of excitons in semiconducting nanostructures making use of high and ultra-high magnetic field. It is also aimed to modeling the conditions in unusual astrophysical objects such as neutron stars.

The experimental simulation of the low-dimensional state of matter with the use of high magnetic fields allows one to study some processes in conditions that are unrealizable in experiments dealing with unaffected technological synthesis of nanostructures in question. This simulation will allow us to save much time and money, which are needed to create, refine, and improve real nanostructures. As a result, it will help us with looking for a proper trend in both the science and technology development in the area of micro- and opto-electronics.

Hence, the proposed R&D program has two aspects. On the one hand, the fundamental physical research will push forward the development of single-crystal semiconductors and nanostructures and simultaneously accelerate the expansion of these structures' use in novel information carriers and optoelectronics. On the other hand, an absolutely new field of physics comes up, dealing with low-dimensional matter and anticipating the possibilities for appearance of new prospective trends in both science and technology.

The authors of the proposed project possess a combination of scientific and technical complexes, which are optimum for the project accomplishment: (i) at the Russian Federal Nuclear Center, the unique techniques and apparatuses for ultra-high magnetic-field generation have been developed, and (ii) at the Ioffe Institute, there exist the molecular-beam-epitaxy techniques and lines for the nanostructures' growth as well as installations for exciton spectroscopy in magnetic fields. As for the technique of exciton spectroscopy, the Ioffe Institute has been one of the world leaders ever since the exciton had been theoretically foretold by Ya.I.Frenkel and experimentally found by E.F. Gross, both working at the Ioffe Institute at that time.

The authors of the project are experienced well enough for intellectual activity in the specified areas of science and engineering. They published many papers on the mentioned problems [see "Literature" subsection in the sections II.1 and II.12]. During the project R&D program accomplishment, the RFNC-VNIIEF applicants will expansively employ the equipment, techniques, and knowledge accumulated at the time of developing the mass-destruction weaponry. The proposed project entirely serves the purposes of the ISTC inasmuch as it opens up good opportunities for scientists and other specialists, which were involved in the weapon development and construction, to use their experience and knowledge for the long-term activity in the civil science and engineering.

All the results on the behavior of matter in ultra-high magnetic fields, to be obtained in the framework of the project, will be entirely new. That is why, at present, it is difficult to guess quantitatively their economical, commercial, and industrial benefits. However, the obtained results will evidently help to understand the processes in semiconductor devices of a new generation, and the appearance of the latter will lead to the rapid improvement of semiconductor micro- and opto-electronics. These results will be also of great interest for astrophysics.
