Electronic Noise Studies of Underdoped High Temperature Superconductors
We use electronic transport noise measurements in order to probe normal state properties of high temperature superconductors with the goal of providing further detail about the environment in which the necessary pairing of electrons occurs. We observe an unusual noise component near and below about …

Monte Carlo simulation for high-frequency intrinsic noise analysis of MOSFET
… introduces a Monte Carlo simulation of intrinsic electronic noise in MOSFETs. Brief reviews of the important aspects of carrier transport, band structure, and Monte Carlo technique are discussed. Based on full band 2D Monte Carlo simulation, a noise analysis platform is utilized. To this end, …

Spatial Coherence-Based Adaptive Acoustic Output Selection for Diagnostic Ultrasound
… shown that LOC is predictive of local signal-to-noise ratio (SNR), and that it is sensitive to incoherent acoustic clutter and temporally-incoherent noise. During B-mode ultrasound imaging, LOC was monitored as MI was adjusted, and the data consistently formed a sigmoid shape. At lower MI values, …

Design of Resistivity Instrumentation for a He3 Cryostat and its Application to the Charge Density Wave Superconductor CuxTiSe2
… samples or doping for elongated samples due to electronic noise. Doping in one sample was found to be between x=0.06 and x=0.065. Values of doping in the second sample had a discrepancy but could be explained by incorrect sample orientation.

Noise detection and transport measurements of spin valve systems.
Electronic noise not only limits the performance of magnetic devices in practical applications but also provides valuable physical insights into these devices. The first part of this thesis discusses how the low frequency noise in magnetic tunnel junctions and giant magnetoresistance devices can be …
