WebDirect tunneling gate leakage current in transistors with ultrathin silicon nitride gate dielectric Abstract: We present a study on the characterization and modeling of direct … WebIn underground environments, conventional direct current (DC) resistivity surveys with a single linear array of electrodes produce fundamentally non-unique inversions. These non-uniqueness and model resolution issues stem from limitations placed on the location of transmitters (TXs) and receivers (RXs) by the geometry of existing tunnels and boreholes.
