Overview

This work demonstrates bandgap nonlinearity and composition-dependent bowing in α-(AlxGa1−x)2O3 epilayers, suggesting implications for Ga2O3 applications.

Key Points

  • The optical bandgap ranged from 5.28 to 7.22 eV, exhibiting significant nonlinearity with a bowing factor of 1.33 eV.
  • X-ray diffraction confirmed high crystalline quality of α-(AlxGa1−x)2O3 epilayers, adhering to Vegard’s law for lattice constants.
  • Analysis involved growth via laser molecular beam epitaxy on m-plane sapphire substrates, assessing surface roughness and rocking curve width.
  • These findings highlight potential for precise bandgap tuning in Ga2O3 for high-performance power electronics.
