Photoelectric absorption cross section of silicon near the band gap from room temperature to sub-Kelvin temperature
C. Stanford, M. J. Wilson, B. Cabrera +6
The use of cryogenic silicon as a detector medium for dark matter searches is gaining popularity. Many of these searches are highly dependent on the value of the photoelectric abso…
High-field Spatial Imaging of Charge Transport in Silicon at Low Temperature
C. Stanford, R. A. Moffatt, N. A. Kurinsky +9
We present direct imaging measurements of charge transport across a 1 cm x 1 cm x 4 mm-thick crystal of high purity silicon (15 k-cm) at temperatures of 5 K and 500 mK. We…
Spatial Imaging of Charge Transport in Silicon at Low Temperature
R. A. Moffatt, N. A. Kurinsky, C. Stanford +10
We present direct imaging measurements of charge transport across a 1 cm 1 cm 4 mm crystal of high purity silicon (20 kcm) at temperatures between 500 mK a…
Similar ultrafast dynamics of several dissimilar Dirac and Weyl semimetals
Chris P. Weber, Bryan S. Berggren, Madison G. Masten +13
Recent years have seen the rapid discovery of solids whose low-energy electrons have a massless, linear dispersion, such as Weyl, line-node, and Dirac semimetals. The remarkable op…
Imaging the Oblique Propagation of Electrons in Germanium Crystals at Low Temperature and Low Electric Field
R. A. Moffatt, B. Cabrera, B. M. Corcoran +11
Excited electrons in the conduction band of germanium collect into four energy minima, or valleys, in momentum space. These local minima have highly anisotropic mass tensors which…
Transient reflectance of photoexcited CdAs
C. P. Weber, Ernest Arushanov, Bryan S. Berggren +3
We report ultrafast transient-grating measurements of crystals of the three-dimensional Dirac semimetal cadmium arsenide, Cd3As2, at both room temperature and 80 K. After photoexci…
Resistance and lifetime measurements of polymer solar cells using glycerol doped poly[3,4-ethylenedioxythiophene]: poly[styrenesulfonate] hole injection layers
Emma Lewis, Bhaskar Mantha, Richard P. Barber
We have performed resistivity measurements of poly[3,4-ethylenedioxythiophene]: poly[styrenesulfonate] (PEDOT:PSS) films with varying concentrations of glycerol. Resistivity is see…
Diffusion of degenerate minority carriers in a p-type semiconductor
C. P. Weber, Eric A. Kittlaus
We report ultrafast transient-grating experiments on heavily p-type InP at 15 K. Our measurement reveals the dynamics and diffusion of photoexcited electrons and holes as a functio…
Rapid diffusion of electrons in GaMnAs
C. P. Weber, Eric A. Kittlaus, Kassandra B. Mattia +5
We report ultrafast transient-grating measurements, above and below the Curie temperature, of the dilute ferromagnetic semiconductor (Ga,Mn)As containing 6% Mn. At 80 K (15 K), we…
Measurement of spin diffusion in semi-insulating GaAs
C. P. Weber, Craig A. Benko, Stanley C. Hiew
We use optical transient-grating spectroscopy to measure spin diffusion of optically oriented electrons in bulk, semi-insulating GaAs(100). Trapping and recombination do not quickl…
Transport and Spectroscopic Studies of the Effects of Fullerene Structure on the Efficiency and Lifetime of Polythiophene-based Solar Cells
Emilee L. Sena, Justin H. Peel, Devin Wesenberg +6
Time-dependent measurements of both power conversion efficiency and ultraviolet-visible absorption spectroscopy have been observed for solar cell blends containing the polymer poly…
Influence of Functionalized Fullerene Structure on Polymer Photovoltaic Degradation
Brian H. Johnson, Enaanake Allagoa, Robert L. Thomas +6
The time dependence of device performance has been measured for photocells using blends containing the conjugated polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]…
Emergence of the persistent spin helix in semiconductor quantum wells
Jake D. Koralek, Chris Weber, Joe Orenstein +4
According to Noethers theorem, for every symmetry in nature there is a corresponding conservation law. For example, invariance with respect to spatial translation corresponds to co…
