  • Band Gap Analysis through UV-Visible Spectroscopy
    Traditionally, the band gap energy is determined through use of a Tauc analysis, by which the band gap energy is related to the absorption coefficient through the following equation,
  • 8. 5: Spectroscopic Characterization of Nanoparticles
    The band gap of the semiconductor quantum dots can be tuned with the size of the particles The minimum energy for an electron to get excited from the ground state is the energy to cross the band gap In an absorption spectra, this is given by the first exciton peak at the maximum wavelength (λmax)
  • Band gap characterization and photoluminescence properties of SiC . . .
    Band-gap characterization and photoluminescence properties of SiC nanowires were investigated by UV-vis absorption spectroscopy and fluorescence photometry, respectively The results showed the SiC nanowire was an indirect transition semiconductor and the band gap energy for the SiC nanowires was 2 85 nbsp;eV
