  • Conference paper (peer-reviewed)abstract
    • Positron annihilation spectroscopy in Doppler broadening mode is used to study epitaxial layers of GaSb 1-x Bi x on undoped GaSb. The samples were grown by Molecular Beam Epitaxy at different temperatures and with different Bi/Sb beam equivalent pressure ratios resulting in Bi concentrations of 0-0.7 %. The results show a relationship between the growth parameters and Doppler broadening parameters. Incorporating Bi into GaSb decreases the vacancy concentration in the epitaxial layers compared to the sample with no Bi in the epitaxial layer.

  • Effect of buffer design on structural and electrical properties of InAs films grown on GaAs substrates
  • 2014
  • In: the 41st international symposium on compound semiconductors, Montepillier, France.
  • Conference paper (peer-reviewed)abstract
    • Different buffer structures were grown by molecular beam epitaxy (MBE) to accommodate the large lattice mismatch of InAs with GaAs substrate. A novel graded digital superlattice (GDSL) buffer design was proposed and compared with the common one-step buffer and linear alloy graded (LAG) buffer designs. Effect of buffer structures on structural and electrical properties of the InAs films was investigated. High quality InAs films were obtained on GaAs substrates.
