Observation of surface charge screening and Fermi level pinning on a synthetic, boron-doped diamond [PDF]
, 1993 Spectroscopic current-voltage (I-V) curves taken with a scanning tunneling microscope on a synthetic, boron-doped diamond single crystal indicate that the diamond, boiled in acid and baked to 500 °C in vacuum, does not exhibit ideal Schottky ...
