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 ... -
Extended infrared photoresponse and gain in chalcogen-supersaturated silicon photodiodes
(AIP Publishing, 2011)Highly supersaturated solid solutions of selenium or sulfur in silicon were formed by ion implantation followed by nanosecond pulsed laser melting. n+p photodiodesfabricated from these materials exhibit gain (external ... -
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 ... -
Microstructural evolution induced by micro-cracking during fast lithiation of single-crystalline silicon
(Elsevier BV, 2014)We report observations of microstructural changes in {100} and {110} oriented silicon wafers during initial lithiation under relatively high current densities. Evolution of the microstructure during lithiation was found ...
