Abstract :
Using low temperature molecular beam epitaxy, we report the growth of thin layers of (Ga1-yIny)1-xTlxAs alloys on InP(001) substrates with thallium incorporation rates up to 12%. The lattice parameters and band gaps of these layers have been determined using Double Crystal X-ray diffraction and optical absorption techniques, respectively. The so-obtained experimental results are found to match the theoretical values predicted by Van Schilfgaarde et a1 for TlAs lattice parameter and band gap.
