Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus
Jimin Kim, Seung Su Baik, Sung Won Jung +5
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black p…
Observation of tunable bandgap and anisotropic Dirac semimetal state in black phosphorus
Jimin Kim, Seung Su Baik, Sae Hee Ryu +7
Black phosphorus consists of stacked layers of phosphorene, a two-dimensional semiconductor with promising device characteristics. We report the realization of a widely tunable ban…
Emergence of Two-Dimensional Massless Dirac Fermions, Chiral Pseudospins, and Berry's Phase in Potassium Doped Few-Layer Black Phosphorus
Seung Su Baik, Keun Su Kim, Yeonjin Yi +1
Thin flakes of black phosphorus (BP) are a two-dimensional (2D) semiconductor whose energy gap is predicted being sensitive to the number of layers and external perturbations. Very…
Extremely high mobility over 5000 cm2/Vs obtained from MoS2 nanosheet transistor with NiOx Schottky gate
Hee Sung Lee, Seung Su Baik, Sung-Wook Min +7
Molybdenum disulfide (MoS2) nanosheet, one of two dimensional (2D) semiconductors, has recently been regarded as a promising material to break through the limit of present semicond…
