Ky. Arutyunov et al., CURRENT-VOLTAGE CHARACTERISTICS AND MAGNETORESISTANCE PECULIARITIES IN BISMUTH MICROBRIDGES, Physica. B, Condensed matter, 218(1-4), 1996, pp. 35-38
A technology of the fabrication of bismuth microbridges with controlle
d geometry and various degrees of perfection of diffuse transport of t
he carriers is realized. Peculiarities on d(2)V/dI(2)(V)P which give i
nformation about the microcontact of the bismuth spectrum, were observ
ed at V = 4.1 mV and V = 11 mV. Some of the dV/dI(V) dependences at a
large bias voltage reveal peculiarities connected with the superconduc
tivity at T-c = 5.9 K.
