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 study of Large scale h-BN film and Graphene/h-BN heterostructure
Kwangnam Yu, Jiho Kim, Chul Lee +5
We synthesize a series of CVD h-BN films and perform critical infrared spectroscopic characterization. For high-temperature (HT, Temp = 1400 degrees) grown h-BN thin film only E1u-…

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…
