Özet
In this study, the solid-liquid phase behavior of an anthracene-interlayer Schottky diode was investigated within the 27 °C-270 °C (300 °K–540 K) range by examining the temperature dependence of its electrical parameters. It was observed that while the diode with a thin interface exhibited changes attributable solely to thermal effects, it did not undergo a solid-liquid phase transition, likely due to nanocrystal confinement effects related to the thickness of the interfacial layer. In contrast, the diode with a thick interface clearly displayed this phase transition process, with significant parameter variations emerging at 216 °C (489 K), corresponding to the bulk melting point of anthracene. These findings were further validated by activation energy plots incorporating effective mass and other Schottky diode parameters, confirming the impact of both phase transitions and structural constraints on charge transport.
