Deactivation of metastable single-crystal silicon hyperdoped with sulfur
(AIP Publishing, 2013)Silicon supersaturated with sulfur by ion implantation and pulsed laser melting exhibits broadband optical absorption of photons with energies less than silicon's band gap. However, this metastable, hyperdoped material ... -
Depth-resolved cathodoluminescence spectroscopy of silicon supersaturated with sulfur
(AIP Publishing, 2013)We investigate the luminescence of Si supersaturated with S (Si:S) using depth-resolved cathodoluminescence spectroscopy and secondary ion mass spectroscopy as the S concentration is varied over 2 orders of magnitude ... -
Methodology for vetting heavily doped semiconductors for intermediate band photovoltaics: A case study in sulfur-hyperdoped silicon
(AIP Publishing, 2013)We present a methodology for estimating the efficiency potential for candidate impurity-band photovoltaic materials from empirical measurements. This methodology employs both Fourier transform infrared spectroscopy and ...
