“…21,22 It should be noted that the formation of the David-star clusters also involves displacements perpendicular to the plane, causing a periodic swelling of the TaS 2 layers. 23,24 This CCDW-Mott phase was found to be sensitive to doping, 21, 25 disorder induced by irradiation, 26 and pressurization.…”

“…As the temperature changes, an unusual response in resistivity and magnetic susceptibility has been observed in typical CDW material systems, such as 1T-VS2 [21], 1T-VSe2 [4,50,59], 1T-TaS2 [26,37,86] and 1T-TaSe2 [82] which is also an indication of CDW transition.…”

Abstract:Recently, two-dimensional (2D) charge density wave (CDW) materials have attracted extensive interest due to potential applications as high performance functional nanomaterials. As other 2D materials, 2D CDW materials are layered materials with strong in-plane bonding and weak out-of-plane interactions enabling exfoliation into layers of single unit cell thickness. Although bulk CDW materials have been studied for decades, recent developments in nanoscale characterization and device fabrication have opened up new opportunities allowing applications such as oscillators, electrodes in supercapacitors, energy storage and conversion, sensors and spinelectronic devices. In this review, we first outline the synthesis techniques of 2D CDW materials including mechanical exfoliation, liquid exfoliation, chemical vapor transport (CVT), chemical vapor deposition (CVD), molecular beam epitaxy (MBE) and electrochemical exfoliation. Then, the characterization procedure of the 2D CDW materials such as temperature-dependent Raman spectroscopy, temperature-dependent resistivity, magnetic susceptibility and scanning tunneling microscopy (STM) are reviewed. Finally, applications of 2D CDW materials are reviewed.

“…Thus, the new peaks cannot be explained by these effects. Finally, as will be shown below, the reduced temperature hysteresis between cooling and warming for these modes are also inconsistent with the scenario of disorder-activated peaks, since disorder tends to either suppress the NC to C transition, or increase the temperature hysteresis [23,24].…”

Distinct surface and bulk charge density waves in ultrathin 1T−TaS2

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 oxidation. We identify new modes originating from C phase CDW phonons that are distinct from those seen in bulk 1T-TaS2. We attribute these to CDW modes from the surface layers. By monitoring individual modes with temperature, we find that surfaces undergo a separate, low-hysteresis NC-C phase transition that is decoupled from the transition in the bulk layers. This indicates the activation of a secondary phase nucleation process in the limit of weak interlayer interaction, which can be understood from energy considerations.
