Abstract:
An electrochemical cell Pt/Ag/AgI/Ag2X/Pt (X=S,Se) has been used as a highly controllable source of S2 or Se2 molecules for n-type doping of GaAs and Ga1As grown by Molecular Beam Epitaxy (MBE). This source produces a pure oeam ot chalcogen dimers at low temperature (200-300°C) and is simply programmed by an applied emf. The response time of the cell is of the order of one second enabling complicated doping profiles to be achieved.
