Scanning tunneling microscopy study of hidden phases in atomically thin 1T-TaS
Wooin Yang, Dowook Kim, Hyoung Kug Kim +1
Lower thermal stability due to thinning often leads to unprecedented hidden phases in low-dimensional materials. Such hidden phases can coexist or compete with preexisting electron…
Thickness dependent charge density wave networks on thin 1T-TaS
Wooin Yang, Dowook Kim, Hyoung Kug Kim +1
We investigate mechanically exfoliated thin 1T-TaS with scanning tunneling microscopy at room temperature. Sample preparation without air exposure enables access to intrinsic c…
In-situ scanning tunneling microscopy observation of thickness-dependent air-sensitive layered materials and heterodevices
Hyoung Kug Kim, Dowook Kim, Dong Guk Lee +5
Quasi-two-dimensional (Quasi-2D) van der Waals (vdW) materials can be mechanically or chemically exfoliated down to monolayer because of their strong intralayer bonding and the wea…
Dimensional crossover of charge order in IrTe with strong interlayer coupling
Hyoung Kug Kim, So Young Kim, C. J. Won +4
Tuning dimensionality in van der Waals materials with finite interlayer coupling has introduced various electronic phase transitions by conventional mechanical exfoliation. Particu…
Superconductivity emerging from a stripe charge order in IrTe2 nanoflakes
Sungyu Park, So Young Kim, Hyoung Kug Kim +15
Superconductivity in the vicinity of a competing electronic order often manifests itself with a superconducting dome, centred at a presumed quantum critical point in the phase diag…
