Novel energy bandgap formation of organic solution doped graphene membrane for semiconductor applications

Abstract

In this work, the electrolyte nano fibrous solution is prepared using corn husk through a chemical process. This study explores the new aspect of producing sizeable and tunable bandgap in graphene by doping organic nanoporous solution as a membrane. The energy bandgap of organic doped graphene membrane varies from 2.313 eV to 2.502 eV. It is noted that the organic nanoporous solution as a membrane also has a bandgap under with (2.665 eV) and without PVA (3.761 eV). The membrane is produced by the phase inversion process. The incorporation of graphene in green solution also exhibits conductive properties like organic nanoporous solution which in terns used as electrolytes to produce electricity. It is the first successful attempt to create a direct graphene bandgap with organic doping but it still requires more research for a better understanding of the properties for future applications. This concept can also be used where bandgap is a very concerning issue. The physical properties of with and without a graphene-based organic membrane are examined by Scanning Electron Microscope Test (SEM), Fourier Transform Infrared Spectroscopy Test (FTIR), and Ultra Violate Test (UV). Sample 4 has a superior surface morphology, which means the particle dispersion is more homogeneous than the others. There are porosities in all the samples.
