A bimorph-based xz scanner and an amplifier, increasing the capacitance and current measurement sensitivities 250-times and 1000-times, respectively, have been built into the cryostat of a deep level transient spectrometer. The setup renders point by point local capacitance-voltage (C–V) at 1 MHz and dc currentvoltage (I–V) measurements using a sharp tip placed into tunnelling distance from the surface...
