In the present work, the piezoelectric properties of TlIn[Formula: see text]Ga[Formula: see text]Se2 single crystals are investigated. Single crystals were grown by the Bridgman–Stockbarger method. The results show that when periodic mechanical vibrations are excited in these crystals, the electrical conductivity is modulated at the same frequency. Measurements of the amplitude values of the piezoconductivity at the same degree of deformation in the dark and under different illumination revealed the presence of a linear relationship between them. The level of the piezosignal also changes linearly depending on the strength of the magnetic field. Thus, TlIn[Formula: see text]Ga[Formula: see text]Se2 crystals have a potential prospect of application in the field of highly sensitive magnetic and light sensors.

This paper has examined the impact of electricity tariff changes to other economic sectors, as well as to potential changes of price levels in the overall economy. In this regard, the authors have applied the Inter-Industry Balance Model and its modification, i.e. Equilibrium Price Multiplier Model. The authors have also empirically built the inter-industry balance and equilibrium price models for the case of Azerbaijan’s economy, and conducted analysis and assessments for this case. The inter-industry balance tables of production and distribution of products and services, officially published by the State Statistical Committee of the Republic of Azerbaijan, were taken as the primary database for this study. It should be noted that the inter-industry balance model for Azerbaijan was built based on 96 sectors of the economy. The model was used to assess the economic impact of electricity price changes in the national economy. Finally, simulations relevant to 10, 20 and 30 percent increase of electricity prices were conducted and potential impacts to Azerbaijan’s economy were assessed. The obtained results were analyzed and summarized.
