Abstract
The results of the crystallization studies of anthracene, tetracene, and pentacene under conditions of vapor phase transport in growth systems with single- and two-zone thermal fields are presented. The features of the phase behavior and thermal stability of the compounds were studied by using the methods of differential scanning calorimetry and thermogravimetric analysis to establish the heating regimes of substances ensuring crystal growth without damage from chemical degradation. Conditions for growing crystals of centimeter scale (0.2–2 cm) were determined for growth systems with single- and two-zone thermal fields. Based on the grown pentacene crystals, a series of field-effect transistors with top drain/source electrodes and top gate were fabricated and their electrical characteristics were studied.
