Implication

Spectroscopic analysis identifies gold donor and acceptor levels in crystalline silicon, highlighting modulated photocurrent phase shift spectroscopy as a robust defect detection tool.

Key Points

To evaluate phase shift spectroscopy of modulated photocurrent as a method for detecting and characterizing gold trap levels in crystalline silicon.
Measured the phase shift of modulated photocurrent in gold-doped crystalline silicon as a function of temperature.
Evaluated phase shift spectral responses across varying modulation frequencies.
Observed three distinct peaks in the phase shift spectra as a function of temperature.
Identified two of the observed spectral peaks as gold donor and acceptor levels, consistent with previously established reference data.
