- Title
Role of electron ‘‘lakes’’ in the negative magnetoresistance effect in the region of Mott hopping conductivity.
- Authors
Ionov, A. N.; Rentzsch, R.; Shlimak, I.
- Abstract
It is shown for doped and compensated germanium that the appearance of negative magnetoresistance under the conditions of Mott hopping conductivity may be due to the presence of a nonuniform spatial distribution of the electron density, the temperature at which the effect appears apparently being determined by the temperature at which the electron gas condenses into electron ‘‘lakes.’’ A ‘‘dead zone’’ effect was also observed in weak magnetic fields, the threshold field increasing with the nonuniformity of the electron distribution. © 1996 American Institute of Physics.
