The focus of this research is to improve upon the bio-semiconductor technology by considering the use of plant extracts and metallic dopant. The plant was Thaumatococcus daniellii and it was extracted using three different solutions i.e. methanol, ethanol and butanol to form sample 1, sample 2 and sample 3, respectively. The plant extract was doped with aluminium under room temperature and pressure. The samples were characterized using UV-Vis spectrometry. It was observed that the chemical reaction of the oxide layer growth pattern varied significantly in all samples considered. Hence, the more stable the growth of the oxide layer, the more d-d transitions expected. These results are also unconnected to the inherent chemical components of Thaumatococcus daniellii that allows for the quick release of pelectrons to the aluminium atom. The band gap of sample 1, sample 2, and sample 3 was calculated as 1.6 eV, 2 eV and 2 eV respectively. There were 3 d-d transitions in the ethanol extract at wavelength k = 612 nm, k = 485 nm & k = 460 nm while there 4 d-d transitions in butanol extract.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
