  • PENIN, Alexandr; SIDORENCO, Anatolie (Technical University of Moldova, 2011)
    Empirical linearly-hyperbolic approximation of the I-V characteristic of diodes and solar cell is presented. This approximation is based on hyperbolic dependence of a current of the p–n junctions on voltage for large ...
  • CASIAN, Anatolie; BALMUS, Ion; DUSCIAC, Viorel (Technical University of Moldova, 2011)
    The physical reasons that lead to deviations from the Wiedemann-Franz law in low-dimensional organic crystals with electronic type conduction are investigated. The kinetic coefficients were modeled as functions of Fermi ...
  • PENIN, Alexandr (Technical University of Moldova, 2011)
    For two-port circuit of direct current the problem of recalculation of the changeable load currents is considered. The approach on the basis of projective geometry is used for interpretation of changes or "kinematics" of ...
