High Performance Silver Diffusive Memristors For Future Computing, Rivu Midya
Masters Theses
Sneak path current is a significant remaining obstacle to the utilization of large crossbar arrays for non-volatile memories and other applications of memristors. A two-terminal selector device with an extremely large current-voltage nonlinearity and low leakage current could solve this problem. We present here a Ag/oxide-based threshold switching (TS) device with attractive features such as high current-voltage nonlinearity (~1010), steep turn-on slope (less than 1 mV/dec), low OFF-state leakage current (~10-14 A), fast turn ON/OFF speeds (<75/250 ns), and good endurance (>108 cycles). The feasibility of using this selector with a typical memristor has been demonstrated by physically integrating them …
Texture And Microstructure Of Ipvd Copper Manganese Seed In 1 Μm & 70 Nm Wide Damascene Trenches, Robert Stuart Brown
Texture And Microstructure Of Ipvd Copper Manganese Seed In 1 Μm & 70 Nm Wide Damascene Trenches, Robert Stuart Brown
Legacy Theses & Dissertations (2009 - 2024)
This thesis describes the grain texture and microstructure of Ionized Physical Vapor Deposition (iPVD) Copper Manganese seed in 1 µm and 70 nm wide damascene trenches. Using Transmission Electron Microscopy (TEM) imaging and diffraction pattern analysis, the grain size and general orientation of the grains were determined. It was found that the 1 µm wide trenches contained larger grains and more texture than that of the 70 nm wide trenches. While this thesis builds upon previous work by Brendan O’Brien in the Dunn group, one significantly different finding will be presented regarding the structure on the sidewall of the trenches. …

The structural properties of bismuth nanoclusters were investigated with transmission high-energy electron diffraction from room temperature up to 525 ± 6 K. The Bi nanoclusters were fabricated by thermal evaporation at room temperature on transmission electron microscope grids coated with an ultrathin carbon film, followed by thermal and femtosecond laser annealing. The annealed sample had an average cluster size of ∼14 nm along the minor axis and ∼16 nm along the major axis. The Debye temperature of the annealed nanoclusters was found to be 53 ± 6 K along the [012] direction and 86 ± 9 K along the [110] …
