| Abstract: | The adsorption of bismuth on Si(110) surfaces has been studied by means of quadrupole mass spectrometry (QMS), LEED and AES. The existence of three main adsorption states (the first, second and third phases) were observed. Two of them (the first and second phases) are two-dimensional phases and the other (the third phase) is a three-dimensional phase. After the completion of the first phase at a high substrate temperature, the LEED pattern showed a clear Si(110) 2 × 3 structure. A shift of the saturation coverage of the two-dimensional phase with the change of the deposition condition was also observed. |
