Symko, Orest George | High Tc rf-biased SQUID | Results are presented on the behavior of a simple rf-biased SQUID made out of YBa2Cu307. It consists of a fractured ceramic pellet stuck together at room temperature. This simple device is shielded by a high Tc tube and it shows the characteristic flux quantization behavior up to 77K. At 4.2K its ma... | High Tc RF-biased SQUID | 1989-03 |

Symko, Orest George | Noise characteristics and instabilities of long Josephson junctions | In a magnetic field, current biased long Josephson junctions exhibit the dynamics of fluxon motion which are affected by fluctuations. These consist of telegraph noise at voltage steps and instabilities due to chaotic behavior. Results on long junctions with McCumber number fic ranging from 10 to 10... | Fluxon motion; Current biased; Instabilities; Telegraph noise; Perturbed sine-Gordon equation | 1989-03 |

Vardeny, Zeev Valentine | Transient photomodulation spectroscopy of nanocrystalline hydrogenated silicon | Transient photomodulation spectra were measured on nanocrystalline Si:H films in the time domain from 10-7 to 10-2 s, spectral range from 0.25 to 1.25 eV, and temperature range from 80 to 300 K. The properties of the spectra are compatible with the presence of two phases, amorphous and crystalline. ... | Transient photomodulation spectroscopy; Nanocrystalline silicon | 1989-03 |
