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…
Interplay of broken symmetry and delocalized excitations in the insulating state of 1-TaS
Xun Jia, Anubhab Haldar, Jungho Kim +13
Coexistence of localized and extended excitations is central to the macroscopic properties of correlated materials. For 5d transition metal compounds, electron correlations alone g…
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…
Photocurrent Imaging of Multi-Memristive Charge Density Wave Switching in Two-Dimensional 1T-TaS2
Tarun Patel, Junichi Okamoto, Tina Dekker +6
Transport studies of atomically thin 1T-TaS2 have demonstrated the presence of intermediate resistance states across the nearly commensurate (NC) to commensurate (C) charge density…
Complete Strain Mapping of Nanosheets of Tantalum Disulfide
Yue Cao, Tadesse Assefa, Soham Banerjee +13
Quasi-two-dimensional (quasi-2D) materials hold promise for future electronics because of their unique band structures that result in electronic and mechanical properties sensitive…
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…
Distinct surface and bulk charge density waves in ultrathin 1T-TaS2
Rui He, Junichi Okamoto, Zhipeng Ye +10
We employ low-frequency Raman spectroscopy to study the nearly commensurate (NC) to commensurate (C) charge density wave (CDW) transition in 1T-TaS2 ultrathin flakes protected from…
