TLDR
In this paper, Bismuth antimonide (composition 80∶20) alloy thin films have been prepared by vacuum deposition at different substrate temperatures and, after annealing, their resistances have been recorded as a function of temperature, between 77 K and 500 K.Abstract:
Bismuth antimonide (composition 80∶20) alloy thin films have been prepared by vacuum deposition at different substrate temperatures and, after annealing, their resistances have been recorded as a function of temperature, between 77 K and 500 K. The observed resistance against temperature behaviour of the films, and the effect of thickness and substrate temperature during deposition of the films, has been explained by considering that these films behave as semiconductors; the overlap between valence and conduction bands being removed due to the presence of antimony, the influence of a quantum size effect and the fact that the grain size of the films formed is a function of thickness and substrate temperature.read more

Electrodeposition of Bi-Sb Alloy Using Cu electrodes
Masato Ohmukai,Akira Tsuyoshi +1 more
TL;DR: In this article, an x-ray diffractometer and an electron probe micro-analysis were used to find no trace of Cu in the obtained alloys and it was concluded that Cu electrodes can be used for the deposition of Bi-Sb alloys, which results in an advantage of availability of the electrode.

Effect of External Current on the Magnetization of Non-Ideal Type II Superconductors
TL;DR: In this article, the influence of external current on the magnetization of non-ideal type II superconductors is explained and it is shown how in the mixed state the external current brings about a particular state of the critical distribution of flux threads allowing a finite total transport current.
