摘要：
Exceptionally pure n-GaAs has been grown without intentional doping by solid-source molecular beam epitaxy (MBE) using arsenic dimers (As2). Peak electron mobilities in the range 2.75-3.32×105 cm 2 V-1 s-1 at temperatures of ≊40-50 K with free-electron densities n=1×1014 cm-3 have been measured for a series of layers grown under a variety of conditions. These mobilities are among the highest recorded for MBE-grown GaAs.
