Query: Dependence of Curie Temperature on the Thickness of Epitaxial (Ga,Mn)As
  Film   We present the magnetotransport properties of very thin (5 to 15 nm) single
(Ga,Mn)As layers grown by low temperature molecular beam epitaxy. A lower
(Ga,Mn)As thickness limit of 5 nm for the ferromagnetic phase and the
dependence of the Curie temperature on (Ga,Mn)As thickness are determined from
electrical transport measurements. The Curie temperature is determined to be 97
K for the thinnest ferromagnetic sample and is found to decrease for increasing
layer thickness. A carrier density of ~7.1$\times10^{20}$ cm$^{-3}$ for the 5
nm thick (Ga,Mn)As layer is determined from Hall measurements. Differences
between magnetotransport properties of thick and thin (Ga,Mn)As layers are
observed and discussed.
