Experimental study of the effect of quantum-well structures on the thermoelectric figure of merit
TL;DR: In this article, it has been shown theoretically that it may be possible to increase the thermoelectric figure of merit (Z$) of certain materials by preparing them in the form of two-dimensional quantum-well structures.

Theoretical investigation of thermoelectric transport properties of cylindrical Bi nanowires
TL;DR: In this paper, a theoretical model for the transport properties of cylindrical Bi nanowires is presented, which shows that the trigonal axis is the most favorable wire orientation for thermoelectric applications.

Electronic transport properties of single-crystal bismuth nanowire arrays
TL;DR: In this article, the electrical transport properties of single-crystal bismuth nanowire arrays embedded in a dielectric matrix were studied and it was shown that the wire boundary scattering is the dominant scattering process for carriers in the undoped singlecrystal Bi nanowires, while boundary scattering was less important for a heavily Te-doped sample.
