Description of the Book:

The temperature dependence of electron mobility of high purity (n 10 to the 15th power/cc) LPE Ga(1-x)Al(x)As layers (x .18) has been studied in the range 25 deg K – 110 deg K to measure the extents of alloy-like and ionized impurity scattering. Values of the alloy scattering parameter Delta E (which may include a contribution from space charge scattering) determined for these samples were found to lie in the range .36 eV to .51 eV, the average being .44 eV. The compensation ratio was found to be about 2, and independent of x. (Author
