  • Correlation of optical transmittance with number of graphene layers 
    John, Benjamin M.; Mugo, Simon W.; Timonah, Nelson S.; Ngumbi, Paul K.; Ngei, K. (American Institute of Physics, 2016)
    Optical transmittance of exfoliated multilayer graphene (MLG) was investigated and cross-referenced with a monolayer purchased from Graphene Supermarket USA, #Y060515. The transmittance was found ...
  • Facile and reliable determination of multilayer graphene thickness using optical microscopy 
    John, Benjamin M.; Ngumbi, Paul K.; Ngei, K.; Mugo, Simon W.; Timonah, Nelson S.; Ngaruiya, James M.
    Optical transmittance of exfoliated multilayer graphene (MLG) was investigated and cross-referenced with a standard monolayer sample. Plots of grayscale values against position on the images were found ...
