Résumé

In this paper, we investigate the effect of the atomic-molecular structure of graphene nanoribbons on their properties, as well as the behavior of these materials under extreme conditions - in electric and magnetic fields. The physical and chemical properties of solids have always attracted the serious attention of researchers. Over the last twenty years, the research area has been shifting towards the physics of semiconductor low-dimensional structures (nanostructures), which is facilitated by the rapid development of technology, the discovery of new materials that can replace existing analogues. The limited charge motion in nanostructures leads to a dimensional quantization, which provokes significant changes in the energy spectrum of charge carriers, phonons, quasiparticles, and promotes the appearance of new phenomena and the physical-chemical properties of substance. Agreater number of investigations are connected with the study of graphene-like materials possessing a unique set of properties, which makes them attractive from the point of view of modern micro-, nano- and optoelectronics (the creation of transistors, nanodiodes, memory elements, optical switches, etc.). One of the main advantages of nanostructures is that the change in configuration and geometric dimensions affects the properties of the system and allows managing these properties [9]. Thus, we can modify the energy spectrum of charge carriers, thereby changing the physical-chemical properties of the system. The purpose of the present research is to study the sensory characteristics of carbon structures on the basis of the tunnel effect, including in the case of curved graphene.
