- 초록
- We present on-going issues on the metal-insulator transition (MIT) and demonstrate the Mott MIT (Mott transition) for an insulator, VO2, with the metallic electronic structure, 3d1. Previously, the exciton-hole-carrier-driven first-order MIT theory is introduced and experimental evidence is exhibited. In particular, we show the temperature dependences of coherent phonons and I-V curves and the MIT measured in metamaterial, and the divergence of the effective mass analyzed by optical method etc. Moreover, a MIT sensor using the Mott MIT is proposed. The MIT sensor will be attracted as a next-generation sensor with very high sensitivity.
