Abstract
We present an experimental investigation of the hot-electron mean free path in ErAs thin films grown on GaAs. Using an Al/Al2O3/Al tunnel junction as a hot-electron source for ballistic electron emission spectroscopy, we investigate ErAs films of thicknesses ~100-~300 Å. Our results indicate a mean free path of order 100 Å for electrons 1-2 eV above the Fermi level at 80 K.
