The present <strong>Thesis</strong> is a fruitful result <strong>of</strong> the continuous collaboration with the supervisor<br />
A. Fujimori and the following excellent co-workers.<br />
Long-years discussion with the supervisor A. Fujimori, who has read the <strong>Thesis</strong><br />
carefully and has given numerous valuable comments, is the backbone <strong>of</strong> this <strong>Thesis</strong>. T.<br />
Mizokawa and K. Kobayashi have instructed the author the photoemission spectroscopy<br />
and have given him continuous advice since he started the present work. He thanks<br />
the colleagues in the laboratory: J.-Y. Son, J. Okamoto, J. Matsuno, J. Okabayashi,<br />
T. Yoshida, Y. Ishikawa, K. Okazaki, H. Ishii, T. Nambu, N. Harima, H. Wakazono, A.<br />

The Yb1−xLuxB12 polycrystals were grown by F. Iga and M. Kasaya at Tohoku<br />
University. The Yb1−xLuxB12 single crystals were grown by N. Shimizu, S. Hiura, F.<br />
Iga, and T. Takabatake at Hiroshima University. Correspondence with F. Iga has <strong>of</strong>ten<br />
been crucial to proceed the present study. Fe1−xCoxSi and FeSi1−xAlx polycrystals were<br />
developed by A. Ohno, T. Tonogai, and H. Takagi at University <strong>of</strong> Tokyo.<br />
The photoemission set up at the Photon Factory, which was used in the study <strong>of</strong><br />
Chapters 3, 4, and 5, was constructed by S. Suga, A. Kimura, T. Matsushita, M.<br />
Tsunekawa (Osaka University), A. Sekiyama (University <strong>of</strong> Tokyo), H. Namatame (Hiroshima<br />
University), H. Ishii, T. Miyahara, and T. Hanyu (Tokyo Metropolitan University).<br />
On measurement, the above members and T. Muro, S. Ueda, T. Iwasaki,<br />
S. Imada (Osaka University), K. Mamiya (Hiroshima University), E. Shigemasa, A.<br />
Kakizaki, K. V. Kaznacheyev (Photon Factory), J. Matsuno, T. Konishi, T. Yoshida<br />
(University <strong>of</strong> Tokyo), and M. Nakamura (Nara University <strong>of</strong> Education) supported the<br />
author. The high-resolution measurements (Chapters 5 and 6) were performed at Hiroshima<br />
University, using the set up improved by Y. Takeda, M. Arita, K. Shimada, H.<br />
Namatame, and M. Taniguchi. <strong>High</strong>est-level photoemission measurements and stimulating<br />
discussion day after day at Hiroshima University, which leads in the physics<br />
<strong>of</strong> <strong>Kondo</strong> insulators, were the highlights <strong>of</strong> the present research. The set up for the<br />
measurements in Chapters 3, 4, 7, and 8 was constructed and has been improved at<br />
University <strong>of</strong> Tokyo by M. Nakamura, A. Sekiyama, and K. Kobayashi. The newly<br />
