Development and study of new hybrid semiconducting systems involving Cd chalcogenide thin films coated by a fullerene derivative

Metal Chalcogenide Nanocrystalline Solid Thin Films

“…IR spectra of the films showed an absorption characteristic around the typical band gap of PbS (0.3-0.5 eV). Mitzithra et al 64 reported a hybrid semiconducting material involving Cd chalcogenide (CdSe or CdTe) coated by fullerene derivative. CdSe and CdTe thin films were electrodeposited by a potentioscan system with a conventional three-electrode setup.…”

Production and identification of highly photoconductive CdSe-based hybrid organic-inorganic multi-layer materials

“…These novel materials could find several interesting applications into various scientific fields, some of them presenting considerable industrial interest, as in photoconductors, photovoltaic devices, opto-electronics, sensors, photodetectors, etc. [1][2][3].…”

“…CdSe, constituting the inorganic part of the hybrid system, is a well-known semiconductor, as referred in our previous works [2,[4][5][6][7] with a direct energy gap (1.7 eV). When electrodeposited, CdSe presents a well-developed cubic zinc-blende structure with a strong (111) preferred orientation [6,8], behaving as a metastable kinetically controlled phase, which can easily be transformed to the thermodynamically stable hexagonal one (wurtzite) by annealing [6].…”

“…A pure hexagonal structure of CdSe has been obtained in the hybrid three-layer materials previously prepared [4]. The organic part, being an electron donor, had induced a significant change in the semiconductive behavior to the final hybrid as compared to the pure inorganic material [2].…”

Hexagonal electrodeposited CdSe in new multi-layer hybrid organic–inorganic semiconductive systems with remarkable high photoconductivity

“…These novel materials could find several interesting applications into various scientific fields, some of them presenting considerable industrial interest, as in photoconductors, photovoltaic devices, opto-electronics, such as organic light-emitting diodes and field-effect transistors, sensors, photodetectors, etc. [1,2].…”
