WebJan 22, 2002 · ABSTRACT The physical bases of the most commonly used methods for the one-dimensional calculation of direct-tunneling current in metal–oxide–semiconductor (MOS) structures (i.e., Bardeen’s approach, the resonant transfer matrix method, and transparency-based approximations) are discussed. 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.
