Electron transfer processes play a crucial role in chemical, physical, and electronic systems, particularly in metal-semiconductor interfaces used in devices like photovoltaics and LEDs. Among these, the Zn/ZnO interface is notable for its practical applicability, owing to ZnO’s wide bandgap and semiconductor properties. Despite theoretical models, the detailed impact of material-specific optical constants on reorientation energy and electron transfer rate remains inadequately characterized. This study theoretically investigates the electronic transition characteristics at the Zn–ZnO interface by calculating the reorientation energy and electron transfer rate using quantum theory and MATLAB-based simulations. Findings demonstrate that electron transfer rate increases with decreased orientation energy, driven by enhanced energy level alignment. Maximum orientation energy (0.408 eV) was observed at 4.06 eV, with corresponding lowest transfer rate, whereas minimum orientation energy (0.334 eV) at 2.119 eV yielded higher transfer rates. The refractive index and dielectric constants derived from extinction and refraction coefficients significantly affect transition parameters. This work provides a detailed theoretical framework combining quantum transition models with empirical refractive and dielectric data to quantify energy alignment and transfer efficiency at a Zn/ZnO interface. The results offer a refined approach to predicting and optimizing electron transfer behavior in Zn/ZnO-based optoelectronic devices, informing future material design for enhanced energy conversion efficiency.

This article examines the historical formation and development of national holidays in the Khorezm oasis by conducting a comparative analysis of Abu Rayhan Beruni’s renowned work "Monuments Left by Ancient Peoples" and other written historical sources. The study seeks to highlight how traditional celebrations in Khorezm originated, evolved, and became culturally significant within the broader historical and social context. Special attention is given to Beruni’s documentation of ancient customs, which is critically compared with contemporary scholarly interpretations and historical literature. By integrating classical narratives with modern academic perspectives, the article offers new insights into the transformation and continuity of national holiday traditions in the region. The analysis also considers different historiographical approaches and emerging viewpoints in order to draw well-founded conclusions about the role of holidays in reflecting collective identity, social cohesion, and historical memory. Ultimately, this study contributes to a more nuanced understanding of the Khorezm oasis’s rich cultural heritage and its connection to the broader legacy of Central Asian civilizations.
