| 抄録: | This paper demonstrates that the spatial distribution of electronic states of an arsenic ion implanted Si (111) substrate can be observed by using a wavelength tunable second harmonic (SH) microscope in a wide photon energy range from 2hω=1.96 to 5.19 eV. The contrast in the SH intensity images between the As-doped area and the nondoped area depends greatly on the SH photon energy. For 2hω>3 eV, optical second harmonic generation (SHG) from the nondoped area was stronger than from the doped area, and the contrast was reversed for 2hω<_＿2.33 eV. The contrast in the SH intensity images was considerably different from that in the linear optical reflection images, indicating that spectroscopic SH microscopy can provide different informations on electronic levels from that associated with the linear optical response. It is suggested that the larger SH intensity from the nondoped area for 2hω＞3 eV results from the resonant SHG enhancement effect associated with the bulk Si E_1(3.4 eV) and E_2 (4.3 eV)gaps. In the case of the doped area, a small resonant enhancement of the SH intensity was observed around 2hω=2.33 eV. This resonance may result from an energy level created by the ion implantation. |
