Differential thermopower images as a probe of many-body effects in quantum point contacts
Yuan Ren, Joshua Folk, Yigal Meir +2
Mesoscopic circuit elements such as quantum dots and quantum point contacts (QPCs) offer a uniquely controllable platform for engineering complex quantum devices, whose tunability…
Low-energy Structural Dynamics of Ferroelectric Domain Walls in Hexagonal Rare-earth Manganites
Xiaoyu Wu, Urko Petralanda, Lu Zheng +5
Domain walls (DWs) in ferroic materials, across which the order parameter abruptly changes its orientation, can host emergent properties that are absent in the bulk domains. Using…
Thickness-dependent Dielectric Constant of Few-layer In2Se3 Nano-flakes
Di Wu, Alexander J. Pak, Yingnan Liu +10
The dielectric constant or relative permittivity of a dielectric material, which describes how the net electric field in the medium is reduced with respect to the external field, i…
Direct Imaging of Nanoscale Conductance Evolution in Ion-Gel-Gated Oxide Transistors
Yuan Ren, Hongtao Yuan, Xiaoyu Wu +5
Electrostatic modification of functional materials by electrolytic gating has demonstrated a remarkably wide range of density modulation, a condition crucial for developing novel e…
Zero-bias Anomaly of Quantum Point Contacts in the Low-Conductance Limit
Y. Ren, W. W. Yu, S. M. Frolov +2
Most quantum point contacts (QPCs) fabricated in high-mobility 2D electron gases show a zero-bias conductance peak near pinchoff, but the origin of this peak remains a mystery. Pre…
Nuclear Polarization in Quantum Point Contacts in an In-Plane Magnetic Field
Y. Ren, W. Yu, S. M. Frolov +2
Nuclear spin polarization is typically generated in GaAs quantum point contacts (QPCs) when an out-of-plane magnetic field gives rise to spin-polarized quantum Hall edge states, an…
