Abstract
Nearly coherent overlayers of CoSi2 were grown on Si(111) by molecular -beam epitaxy and examined by an in situ scanning-tunneling microscope at 77 K. The quantum-size effect in CoSi2 overlayers was demonstrated using scanning-tunneling microscopy. Subbands in the LAMBDA1 and LAMB DA3 energy bands along the GAMMAL symmetry line were observed, and the observed subband spacings agree well with independent band-structure computations.
