Is the intrinsic conductivity of AlGaSb grown at low temperatures n or p type

In liquid phase epitaxial GaSb and AlGaSb grown at low temperatures some papers reported p‐type conductivity and others observed the conversion to n‐type conductivity. In this paper, it is shown that p‐type conductivity is intrinsic at growth temperatures down to 350 °C and that the extrinsic impurities influence the concentration at lower growth temperatures than 350 °C.
