Thermoelectric power of tellurium thin films and its thickness and temperature dependence
TLDR
In this article, it was shown that thermoelectric power is independent of temperature and is also independent of thickness, over the range of temperatures and thicknesses investigated, and the results were discussed on the basis of size effect and temperature effect theories.Abstract:
Tellurium thin films of thicknesses between 25 and 200 nm have been vacuum-deposited on glass substrates at room temperature in a vacuum of 5×10−5torr. The thermoelectric power measurements on these films have been carried out, after annealing, in the temperature range from 300 to about 500 K. It is found from the study that thermoelectric power is independent of temperature and is also, apparently, independent of thickness, over the range of temperatures and thicknesses investigated. The results are discussed on the basis of size effect and thermoelectric effect theories.read more

Vapor-solid growth of p-Te/n-SnO2 hierarchical heterostructures and their enhanced room-temperature gas sensing properties.
TL;DR: When exposed to CO and NO2 gases at room temperature, Te/SnO2 hierarchical heterostructures changed the resistance in the same trend and exhibited much higher responses and faster response speeds than the Te nanotube counterparts.

Less known facts and findings about TiO2 nanotubes.
TL;DR: The present mini-review highlights less known but important aspects, such as the formation of spaced nanotubes with adjustable interspacing that is achieved in a few specific organic electrolytes, and strong effects of the metallic Ti substrate which significantly affect the growth of the tubes.

Electrical properties of tellurium thin films
TL;DR: In this paper, the structural properties of Au-nucleated Te thin-film transistors with 3-mil channels were studied and correlated with observed structural properties, and it was found that less-than-monolayer gold films can act as nucleation sites and stimulate the growth of large crystallites in deposited Te films.
