Exploring the Temperature-Dependent Microelectrical Characteristics of Organic-Silicon Heterojunctions in the Absence of Luminance

“…Briefly, as reported earlier, O-PDI was synthesized using PTCDA, oleylamine, and imidazole in a molar ratio of 1:2.4:36, kept in a sealed vial with an inert atmosphere (nitrogen gas was purged through the reaction mixture) with constant stirring at 120 °C for 7 h to obtain the solid product.…”

“…Our objective is to analyze the electrical characteristics of an Ag/PDI/p-c-Si/Al device through the incorporation of a PDI organic layer between silicon (Si) and silver (Ag), to conduct a comparative investigation between two organic–semiconductor devices, designated as A and B (Ag/PDI/p-c-Si/Al), both containing n -type perylene derivatives. Device A integrates N , N ′-di­(cis-9-octadecen-1-yl)­perylene-3,4,9,10-tetracarboxylic diimide (O-PDI), characterized by a lengthy aliphatic chain with unsaturation at the C-9 position (oleylamine) positioned at the imide site of perylene, leading to a three-dimensional (3D) configuration . In contrast, Device B incorporates N , N ′-di­(octadecyl)­perylene-3,4,9,10-tetracarboxylic diimide (OD-PDI), wherein a lengthy aliphatic chain (octadecylamine) resides at the imide site of perylene, resulting in a more planar structure, depicted in Figure .…”
