Autor: Ahn, Sung Joon, Moon, Pilkyung, Kim, Tae-Hoon, Kim, Hyun-Woo, Shin, Ha-Chul, Kim, Eun Hye, Cha, Hyun Woo, Kahng, Se-Jong, Kim, Philip, Koshino, Mikito, Son, Young-Woo, Yang, Cheol-Woong, Ahn, Joung Real

Quantum states of quasiparticles in solids are dictated by symmetry. Thus, a discovery of unconventional symmetry can provide a new opportunity to reach a novel quantum state. Recently, Dirac and Weyl electrons have been observed in crystals with dis

Autor: Jeon, Cheolho, Shin, Ha-Chul, Song, Inkyung, Kim, Minkook, Park, Ji-Hoon, Nam, Jungho, Oh, Dong-Hwa, Woo, Sunhee, Hwang, Chan-Cuk, Park, Chong-Yun, Ahn, Joung Real

Publikováno v: SCIENTIFIC REPORTS 3, 2725,2013

For graphene to be used in semiconductor applications, a wide energy gap of at least 0.5 eV at the Dirac energy must be opened without the introduction of atomic defects. However, such a wide energy gap has not been realized in graphene, except in th
