Methodology for vetting heavily doped semiconductors for intermediate band photovoltaics: A case study in sulfur-hyperdoped silicon

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 low-temperature photoconductivity to calculate a " performance figure of merit " and to determine both the position and bandwidth of the impurity band. We evaluate a candidate im...

On the Universality of Inversion Layer Mobility in Si MOSFET's: Part I-Effects of Substrate Impurity Concentration

This paper reports the studies of the inversion layer mobility in nand p-channel Si MOSFET's with a wide range of substrate impurity concentrations to 10l8 cm-"). The validity and limitations of the universal relationship between the inversion layer mobility and the effective normal field (E,E) are examined. It is found that the universality of both the electron and hole mobilities does hold up...

Stimulated terahertz stokes emission of silicon crystals doped with antimony donors.

Stimulated Stokes emission has been observed from silicon crystals doped by antimony donors when optically excited by radiation from a tunable infrared free electron laser. The photon energy of the emission is equal to the pump photon energy reduced by the energy of the intervalley transverse acoustic (TA) g phonon in silicon (approximately 2.92 THz). The emission frequency covers the range of ...

Phosphorus-doped silicon nanocrystals exhibiting mid-infrared localized surface plasmon resonance.

Localized surface plasmon resonances (LSPRs) enable tailoring of the optical response of nanomaterials through their free carrier concentration, morphology, and dielectric environment. Recent efforts to expand the spectral range of usable LSPR frequencies into the infrared successfully demonstrated LSPRs in doped semiconductor nanocrystals. Despite silicon's importance for electronic and photon...
