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…
Coexistence of Quasi-two-dimensional Superconductivity and Tunable Kondo Lattice in a van der Waals Superconductor
Shiwei Shen, Tian Qin, Jingjing Gao +8
Realization of Kondo lattice in superconducting van der Waals materials not only provides a unique opportunity for tuning the Kondo lattice behavior by electrical gating or interca…
Observation and manipulation of a phase separated state in a charge density wave material
Sean M. Walker, Tarun Patel, Junichi Okamoto +8
The 1T polytype of TaS has been studied extensively as a strongly correlated system. As 1T-TaS is thinned towards the 2D limit, its phase diagram shows si…
Inducing and tuning Kondo screening in a narrow-electronic-band system
Shiwei Shen, Chenhaoping Wen, Pengfei Kong +7
Although the single-impurity Kondo physics has already been well understood, the understanding of the Kondo lattice problem where a dense array of local moments couples to the cond…
Roles of the Narrow Electronic Band near the Fermi Level in 1T-TaS-Related Layered Materials
Chenhaoping Wen, Jingjing Gao, Yuan Xie +9
Here we use low-temperature scanning tunneling microscopy and spectroscopy (STM/STS) to reveal the roles of the narrow electronic band in two 1T-TaS-related materials (bulk 1T-…
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…
Ultrafast transmission electron microscopy on dynamic process of a CDW transition in 1T-TaSe2
Shuaishuai Sun, Linlin Wei, Zhongwen Li +7
Four-dimensional ultrafast transmission electron microscopy (4D-UTEM) measurements reveal a rich variety of structural dynamic phenomena at a phase transition in the charge-density…

A. W. Tsen, R. Hovden, D. Z. Wang +10
The layered transition metal dichalcogenides host a rich collection of charge density wave (CDW) phases in which both the conduction electrons and the atomic structure display tran…
Single Crystal Growth, Transport, and Electronic Band Structure of YCoGa
