Electrical and photoelectrical set-ups

Electrical and photoelectrical set-ups

Electrical characterization in dark and under illumination and Hall investigations by measurements and modelling of experimental curves:

  • current-voltage (I– V) at different temperatures T, in DC and AC regime
  • capacitance-voltage (C– V), capacitance-frequency (C – f) and capacitance-time (C – t)
  • polarization-voltage (P– V)
  • I– T and R – T at different bias voltages
  • Photocurrent spectra (I– λ) under modulated and continuous light regime
  • Hall measurements: V–Icharacteristics for different applied currents, magnetic fields and T
