Abstract

New spirocompounds have been prepared and their temperature dependences of the electrical conductivity and Seebeck are coefficient studied. Measurements were performed using thin-film samples deposited from the solution. All investigated compounds have semiconducting characteristics. The values of some fundamental parameters (thermal activation energy, ratio of carrier mobilities, etc) have been determined. A correlation between semiconducting properties and molecular structure of the compounds is established.
