A ${\mathrm{TiS}}_{2}$ crystal with a layered structure was found to have a large thermoelectric power factor. The in-plane power factor ${S}^{2}/\ensuremath{\rho}$ at 300 K is $37.1\ensuremath{\mu}{\mathrm{W}/\mathrm{K}}^{2}\mathrm{cm}$ with resistivity (\ensuremath{\rho}) of 1.7 m\ensuremath{\Omega} cm and thermopower (S) of -251 \ensuremath{\mu}V/K, and this value is comparable to that of the best thermoelectric material, ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}$ alloy. The electrical resistivity… 
Natural Superlattice Material: TiS$$_{}$$-Based Misfit-Layer Compounds
Layered titanium disulfide has been reported to show a high power factor due to its two-dimensional electronic state. However, its high thermal conductivity makes the conversion efficiency too small
Thermal conductivity of the quasi-one-dimensional materials TaSe3 and ZrTe3
The high breakdown current densities and resilience to scaling of the metallic transition-metal trichalcogenides ${\mathrm{TaSe}}_{3}$ and ${\mathrm{ZrTe}}_{3}$ make them of interest for possible
Ordering in Intercalated Ni Atoms and Electron Density Distributions of Layered Compounds NixTiS2
A structural study of layered compounds Ni x TiS 2 ( x = 0.30, 0.37, and 0.63) by X-ray and electron diffraction analyses was performed to investigate both the ordered atomic arrangement and

TLDR
The successful fabrication of Te/TiS2 heterostructure nanocables with enhanced thermoelectric (TE) performance by a two-step route is presented, which is scalable for practical nanodevice applications and is expected to open up new application possibilities in nanoscale TE devices based on individual Te/ TiS2heterostructure Nanocables.
Thermoelectric Properties of TiS 2 type materials
