    • Design and operation of a monolithic field emission triode 
      Legg, James Derek (Texas A&M University. Libraries, 1994)
      Due to limitations of semiconductor-based microelectronics, a clear need for a superior technology exists. Field emission vacuum microelectronics is one such technology that possesses the potential to overtake the ...
    • Direct Write Laser Lithography For Discretionary Interconnections 
      Karunatileka, Muditha A. (1986)
      A novel method for making discretionary interconnections involves direct writing on wafer using a precision laser beam and metallization using the lift off process. After experimenting with several line thicknesses, ...
    • Effects of Lateral Confinement in a Superlattice 
      Silva, Julio Toro (1996)
      We discuss the progress that we have had in studying the effects that lateral confinement has in the electronic bandstructure of a superlattice, and consequently, on its current-voltage characteristics. This study has been ...
    • Electron field emission in porous silicon 
      Yue, Wing Kong (Texas A&M University. Libraries, 1991)
      Anodization of a heavily doped silicon wafer followed by oxidation can build a structure of an insulated layer with vertical voids on the substrate. When a positive potential is applied on the top of the insulating layer, ...
    • Fabrication of channeling masks for Ion Projection Lithogrphy 
      Ghatak-Roy, Amiya R. (Texas A&M University. Libraries, 1994)
      For sub-0.5 $mu$m feature sizes in VLSI circuits, Ion Projection Lithography shows good promise. One of the key components for this type of lithography is the availability of a suitable mask. Present work involved the ...
    • Gate adjusted resonant tunnel diode device and method of manufacture 
      Weichold, Mark H.; Kinard, William B.; Kirk, Wiley P. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1992-03-03)
      A gated resonant tunneling diode has a semiconductor mesa formed on a semiconductor substrate, a tunneling barrier layer between the mesa and the substrate, and a gate layered over the substrate about the mesa and aligned ...
    • Investigation Into The Viability Of A Magnetic Thin Film As An Analog, Nonvolatile Memory Device 
      Grein, Matthew (1993)
      A %50Co-50%Fe magnetic film of 1000Å has been used as the memory element fabricated on a silicon substrate to be used as a nonvolatile memory with read/write capabilities. A Hall element has been employed to detect the ...
    • Investigation of Four Circuit Designs for Mutlivalued Logic Applications 
      Chinchilla, Kenneth (1997)
      Multivalued logic (MVL) circuits display more than the two states (LOW and HIGH) exhibited by traditional logic circuits. A ternary logic circuit, for example, may contain states such as HIGH, MEDIUM, and LOW. The demands ...
    • Magnetostrictive Current Sensor Development Using Fiber Optics 
      Williams, Stephen E. (1991)
      The ability to develop a fiber optic current sensor utilizing the magnetostrictive characteristics of nickel (Ni) has been proven. A Mach-Zehnder interferometer, which had a 2. 5-μm layer of Ni 15-cm long on its sensing ...
    • Oxidized porous silicon field emission devices 
      Yue, Wing K.; Parker, Donald L.; Weichold, Mark H. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1995-07-04)
      A low voltage vacuum field emission device and method for manufacturing is provided. The devices are fabricated by anodizing a heavily doped silicon wafer substrate (12) in concentrated HF solution, forming extremely sharp ...
