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
