The Photorefractive Effect In Batio3, Tom Savard
The Photorefractive Effect In Batio3, Tom Savard
Honors Theses, 1963-2015
The photorefractive effect was observed in a sample of BaTiO, crystal. In two-beam coupling experiments, the crystal failed to amplify the signal beam even though experimental configurations that provided other researchers with large gains were used. However, beam fanning, a two-beam coupling effect, was observed. The unmeasurable gain of our crystal in twc-beam coupling experiments might be due to multiple domains in the crystal or competition between hole and electron charge carriers. In addition, a self-pumped phase conjugate mirror was made using the "cat" configuration. The formation of the phase conjugate mirror in the crystal was observed using the image …
The Quantum Magneto Effect Of Bismuth, Omar Kerem Durdag
The Quantum Magneto Effect Of Bismuth, Omar Kerem Durdag
Honors Theses, 1963-2015
Using a standard field modulation technique, the de Haas-van Alphen effect was measured in bismuth for various crystal orientations. Measurements performed using a d.c. magnetic field that was ramped up from -0.05 T to -0.6 T at 4.2 K with a w.01 T modulating field. Data shows a variation of dHvA period with orientation that is in good agreement with the results of Bhargava'.
Modeling Radon Transport And Entry, Michael John Bergmann
Modeling Radon Transport And Entry, Michael John Bergmann
Honors Theses, 1963-2015
Techniques and devices for measuring the emanation power and permeabdity of soil samples are developed. A Monte Carlo simulation is used to model the transport of radon to 112 basements in Minnesota. Correlation between this model and the measured indoor radon concentration is compared to other leading models' correlations. This model has been found to have the strongest correlation.
