This paper describes some GaAs probe tunneling experiments which exhibit the usefulness and reliability of this bulk tunneling method. Tunneling characteristics were observed for all superconducting counter-electrodes, and the measured ratios of superconducting energy gap to transition temperature were in good agreement with measurements by other techniques. Also described are the effects of contact pressure and a novel in situ surface cleaning technique for removing chemically contaminated surface layers. © 1970 The American Institute of Physics.
