Synthesis and Characterization of Zinc Coated Carica papaya Extracts for Solid-State Application

Abstract:

The evolution of semiconductor from the conventional type to organic semiconductor has not convincingly shown that it is eco-friendly both in the short and long term. This research presents the green solution bio-semiconductor that was synthesized from zinc coated carica papaya. It was observed that carica papaya extracts do not respond significantly to the extracting solution (methanol, ethanol and butanol). The band gap of sample 1 (extract in methanol solution), sample 2 (extract in ethanol solution) and sample 3 (extract in butanol solution) was calculated as 1.98 eV, 2.01eV and 1.93 eV respectively. Further research is therefore recommended for the perfection of the bio-semiconductor.
