Scanning tunneling microscopy and photoemission electron microscopy studies on single crystal Ni2P surfaces.

The surface structures of nickel phosphide (Ni2P) single crystals were studied by scanning tunneling microscopy (STM) and photoemission electron microscopy (PEEM). Atomically resolved 1 x 1 images of the Ni2P(0001) and (1010) surfaces are successfully obtained with STM, whose respective dimensions of (0.59 nm x 0.
