TL;DR: In this article, the vibrational properties of the transition metal dichalcogenide $1T\text{\ensuremath{-}}{\mathrm{TaS}}_{2}$ for various thicknesses in the high-temperature (undistorted) phase and the lowtemperature commensurate charge density wave (CDW) phase were investigated.

TL;DR: In this paper, a phase diagram of domain morphology is developed in the space of flux and the precursor stoichiometry, in which the triangular compact, fractal and dendritic domains are identified.

TL;DR: It is demonstrated that substrate surface roughness is a primary extrinsic factor in CCDW transition temperature and hysteresis, where higher roughness leads to smaller transition hyste Resis, which enables the potential for engineering CDW phase transitions.

TL;DR: In this article, the authors demonstrate direct and controllable synthesis of ultra-thin 1T-TaS2 films and domains via powder vapor deposition on a variety of substrates (sapphire, SiO2/Si, and graphene).

TL;DR: In this paper, a thin film piezoelectric actuator is used to correct mirror figure errors due to fabrication, mounting and alignment, using calibration and a one-time figure adjustment on the ground.
