    Effects of the overlap between wave functions of impurity centers on the activation energy of hopping conduction (2000)

    Notes: Abstract The hopping conductivity σ3 has been studied in samples of slightly counterdoped crystalline Si: B with a boron concentration of 2×1016 cm−3〈N〈1017 cm−3 and a compensation of 10−4≤K≤10−2. It is found that at K≤10−3 the activation energy ε3 is not lower (as it must be according to classical notions at finite K) but larger than the value εN=e 2 N 1/3/κ, where e is the electronic charge and κ is the dielectric constant. With decreasing N, the energy ε3 drops slower and, with decreasing K, grows faster than follows from the standard theory. At K≤10−4, ε3 is higher than ε N by a factor of 1.5–2. The result is explained by the effect of the overlap between wave functions of neighboring impurity centers on the structure of the impurity band.

    Virostatic action of rimantidin studied on a phage-bacterium model (1976)
    Springer
    Bulletin of experimental biology and medicine 81 (1976), S. 704-706

    ISSN: 1573-8221
    Keywords: rimantidin ; phage and bacterial RNA polymerase ; DNA polymerase

    Notes: Abstract The action of rimantidin on reproduction of phages T3, T4, and λ was investigated. The maximal inhibitory action of the compound was observed between the first and sixth minute of infection with phage T3, but no such effect was observed on replication of phages T4 and λ. It is postulated on the basis of the results of incorporation of labeled precursors into phage DNA, RNA, and protein and the character of manifestation of the action of the compound on the phage yield that the inhibitory effect of rimantidin is evidently determined by its effect on bacterial and phage RNA polymerases, mainly on the latter.
