Observation of optical absorption correlated with surface state of topological insulator
Jiwon Jeon, Kwangnam Yu, Jiho Kim +3
We performed broadband optical transmission measurements of Bi2Se3 and In-doped Bi(1-x)In(x)2Se3 thin films, where in the latter the spin-orbit coupling (SOC) strength can be tuned…

Gate tunable optical absorption and band structure of twisted bilayer graphene
Kwangnam Yu, Van Luan Nguyen, Tae Soo Kim +5
We report the infrared transmission measurement on electrically gated twisted bilayer graphene. The optical absorption spectrum clearly manifests the dramatic changes such as the s…

Infrared spectroscopic study of carrier scattering in gated CVD graphene
Kwangnam Yu, Jiho Kim, Joo Youn Kim +4
We measured Drude absorption of gated CVD graphene using far-infrared transmission spectroscopy, and determined carrier scattering rate (g) as function of the varied carrier densit…
