Thermoelectric properties of wires Bi-6at%Sb and Bi-8at%Sb under elastic stretches

Autor: Popov, Ivan

Publikováno v: Moldavian Journal of the Physical Sciences, Vol 4, Iss 4, Pp 443-448 (2005)

Thin Bi1-xSbx wires with stibium concentration of 6 and 8at% in the free state and under elastic stretches are studied. Under 6-8% stretches the electron topological transition semiconductor-semimetal is found. The power factor is calculated.

An analysis of the accuracy of short-wave and long-wave asymptotics for stationary Lamb waves in the isotropic layer

Autor: Astapov Yaroslav, Lukin Aleksei, Popov Ivan

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 17, Iss 3 (2024)

In the paper, the exact and asymptotic approximate solutions for symmetric and antisymmetric Lamb waves in the homogeneous isotropic elastic film have been analyzed. Using the numerical methods of the theory of continuation of solutions of nonlinear
