Negative magnetoresistance in n-type germanium and its analysis based on quantum theory of this effect
Polyanskaya T. A., Saidashev I.I.
A comparison of the experimental and theoretical data shows that the effect of interelectronic repulsion on magnetoresistance must be taken into account. The interaction constant of electrons and the relaxation time of the wave function, which turned out to be close to the decay time of single-electron excitations, are examined.
