Site Preferences and "Coloring Problem" in Cu-doped BiMnO Quadruple Perovskite
Cheng Peng, Mingyu Xu, Yang Zhang +3
Lightly Cu-doped BiMnO (x = 0.05, 0.10, and 0.15) was investigated using high-pressure synthesis, single-crystal X-ray diffraction, pair distribution function (PDF) anal…
Melting point depression of charge density wave in 1T-TiSe due to size effects
Saif Siddique, Mehrdad T. Kiani, Omri Lesser +13
Classical nucleation theory predicts size-dependent nucleation and melting due to surface and confinement effects at the nanoscale. In correlated electronic states, observation of…
Nanoscale Polar Landscapes in Quantum Paraelectric SrTiO3
Yang Zhang, Suk Hyun Sung, Nishkarsh Agarwal +5
SrTiO3 is a textbook quantum paraelectric, with ferroelectricity purportedly suppressed by quantum fluctuations of ionic positions down to the lowest temperatures. The precise real…
Melting of Charge Density Waves in Low Dimensions
Jeremy M. Shen, Alex Stangel, Suk Hyun Sung +9
Charge density waves (CDWs) are collective electronic states that can reshape and melt, even while confined within a rigid atomic crystal. In two dimensions, melting is predicted t…
Endotaxial Stabilization of 2D Charge Density Waves with Long-range Order
Suk Hyun Sung, Nishkarsh Agarwal, Ismail El Baggari +10
Charge density waves are emergent quantum states that spontaneously reduce crystal symmetry, drive metal-insulator transitions, and precede superconductivity. In low-dimensions, di…
Limits to the strain engineering of layered square-planar nickelate thin films
Dan Ferenc Segedin, Berit H. Goodge, Grace A. Pan +15
The layered square-planar nickelates, NdNiO, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed…
Two-dimensional charge order stabilized in clean polytype heterostructures
Suk Hyun Sung, Noah Schnitzer, Steve Novakov +15
Compelling evidence suggests distinct correlated electron behavior may exist only in clean 2D materials such as 1T-TaS2. Unfortunately, experiment and theory suggest that extrinsic…
Direct Visualization of Trimerized States in 1T'-TaTe
Ismail El Baggari, Nikhil Sivadas, Gregory M. Stiehl +4
Transition-metal dichalcogenides containing tellurium anions show remarkable charge-lattice modulated structures and prominent interlayer character. Using cryogenic scanning transm…
Atomic Lattice Disorder in Charge Density Wave Phases of Exfoliated Dichalcogenides (1T-TaS2)
Robert Hovden, Adam W. Tsen, Pengzi Liu +8
Charge density waves (CDW) and their concomitant periodic lattice distortions (PLD) govern the electronic properties in many layered transition-metal dichalcogenides. In particular…
