Longitudinal recording on FePt and FePtX (X = B, Ni) intermetallic compounds
Near field recording on high coercivity FePt intermetallic compound media using a high Bsat write element was investigated. Untextured FePt media were prepared by magnetron sputtering on ZrO2 disks at a substrate temperature ...
Low-frequency noise in spin valve sensors
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
Experimental demonstration of all-optical CDMA using bipolar codes
Fiber optic networks capable of supporting a large pool of subscribers, many simultaneous users, and high data rates are receiving heightened interest as solutions to a growing communications need. The experiments reported ...
Investigating the electronic properties of carbon nanostructures with scanning tunneling microscopy
Utilizing the scanning tunneling microscope, the electronic and structural properties of a variety of carbon based nanostructures, are explored. Among these, threefold electron scattering on graphite generated by vacancies ...
Electrical transport in a single-electron transistor coupled to a tunable environment
A novel model system is developed to study the effects of the environment on transport properties of a superconducting single-electron transistor (S-SET). The impedance of a two-dimensional electron gas (2DEG) 50 nm below ...
Development of an ion/electron plasma spectrometer
This thesis details the development of the Miniaturized Electrostatic DUal top-hat Spherical Analyzer (MEDUSA) instrument, including calibration, simulation, and data processing software. MEDUSA combines two-species ...
