Phys { +GateOxide { oxideTrap = "Pure"; OxideTrap { Pure { Nt = 1e19 "cm^-3"; // trap concentration type = "negative"; // charge state occupancy = 0.001; // trap occupancy energy = 2 "eV"; // trap energy level } } } +Gate { Contact { Ohmic { Ew = -0.5 eV; }} } }A charge state of ("negative"), 0 ("neutral"), and ("positive") can be chosen. The trap charge is self-consistently considered in the POISSON equation. The possible keyword values are shown in Table D.7.
