A. Triki et al., Multiconfigurate character of the DX center and statistical analysis of transport data in Si-doped AlxGa1-xAs, PHYS ST S-B, 227(2), 2001, pp. 541-547
Two statistics are developed using the multiconfigurate character of the DX
center to analyse donors in n-type AlxGa1-xAs:Si. The first statistics is
derived assuming that the conduction electrons arise exclusivelv from DX ce
nters. The second statistics supposes the existence of shallow donors in ad
dition to the deep DX center. Experimental Hall data, obtained in AlxGa1-xA
s:Si grown by metalorganic chemical vapor deposition. are interpreted using
these statistical calculations.
