“…Semiconducting polymers (SCPs) have established themselves as outstanding organic semiconductors for widespread utilization in the rapidly growing area of plastic electronics. Because of their intrinsic molecular self-assembly propensity, SCPs’ optoelectronic characteristics can be easily adjusted [ 1 , 2 , 3 , 4 , 5 ]. SCPs have good solution rheology, making them appealing for use as an active layer of semiconductor devices in roll-to-roll manufacturing for flexible electronics.…”

Extended π-conjugation with backbone-planarity-driven π-π stacking dominates charge transport in semiconducting polymers (SCPs). The roles of SCP film morphology and macromolecular conformation concerning the substrate in influencing charge transport and its impact on device performance have been a subject of extensive debate. Face-on SCPs promote out-of-plane charge transport primarily through π-π stacking, with conjugated polymeric chains assisting transport in connecting crystalline domains, whereas edge-on SCPs promote in-plane charge transport primarily through conjugation and π-π stacking. In this work, we fabricated three different types of devices, namely, organic field effect transistors, organic Schottky diodes, and organic bistable memristors, as representatives of planar and vertical devices. We demonstrate that a planar device, i.e., an organic field effect transistor, performs well in an edge-on conformation exhibiting a field-effect mobility of 0.12 cm2V−1s−1 and on/off ratio >104, whereas vertical devices, i.e., organic Schottky diodes and organic memristors, perform well in a face-on conformation, exhibiting exceptionally high on/off ratios of ~107 and 106, respectively.

“…For instance, direct bandgap semiconductors have been widely employed in signal processing, energy supply, display technology, solar cells, photodetectors, optical sensors, and medical imaging, which lead to the engineering of optoelectronic devices in both the economic and technological sectors (Colak, 1993;Benkabou et al, 2000;Tamargo, 2002;Adachi, 2009;Deng et al, 2009;Iqbal M. A. et al, 2022). Their characteristics are also size-dependent, and recently, attention has been diverted to the 2023 Nobel Prize in chemistry, which was awarded for the discovery of quantum dots due to their sizedependent display and photodetection applications (Abdullah et al, 2023). In addition to the size, chemical doping and dopant concentration are also important factors that enable the tuning of the material characteristics for the fabrication of novel low-cost, highly efficient devices.…”

“…Such properties can be acquired by changing the compounds' composition so that they can function favorably at a wide range of wavelength spectra. The direct bandgap of group II-VI semiconductors involving cadmium-substituted zinc selenide (CdZnSe) alloys makes them an attractive candidate for use in fabricating various devices in the optoelectronic, photonic, and photovoltaic industries (Colak, 1993;Benkabou et al, 2000;Tamargo, 2002;Adachi, 2009;Iqbal M. A. et al, 2022;Hile et al, 2022;Wang et al, 2022;Abdullah et al, 2023).…”

A change in the composition and dopant content of selective atoms in a material leads to their new desired properties by altering the structure, which can significantly improve the performance of relevant devices. By acknowledging this, we focused on characterizing the optoelectronic and structural properties of cadmium-substituted zinc selenide (Zn1-xCdxSe; 0 ≤ X ≤ 1) semiconductors using density functional theory (DFT) within the generalized gradient approximation (GGA), EV-GGA, and mBJ approximations. The results proved the cubic symmetry of the investigated materials at all Cd concentrations (0, 0.25, 0.50, 0.75, and 1). Although a linear surge in the lattice constant is observed with the change in Cd content, the bulk modulus exhibits a reverse trend. These materials are observed to be direct bandgap semiconductors at all Cd concentrations, with a decrease in electronic bandgap from 2.76 eV to 1.87 eV, and have isotropic optical properties, showing their potential applicability as a blue-to-red display. The fundamental optical properties of the materials, such as optical conductivity, reflectance, refractive index, absorption, and extinction coefficient, are also discussed. These outcomes provide a computational understanding of the diverse applications of Zn1-xCdxSe semiconductors in optoelectronic, photonic, and photovoltaic devices, particularly for a visible-range display.
