Novel hysteresis effect in ultrathin epitaxial Gd₂O₃ high-k dielectric

Charge trapping in ultrathin high-k Gd₂O₃ dielectric leading to appearance of
 hysteresis in C–V curves is studied by capacitance-voltage, conductance-frequency and
 current-voltage techniques at different temperatures. It was shown that the large leakage
 current at a negati...

description Charge trapping in ultrathin high-k Gd₂O₃ dielectric leading to appearance of
 hysteresis in C–V curves is studied by capacitance-voltage, conductance-frequency and
 current-voltage techniques at different temperatures. It was shown that the large leakage
 current at a negative gate voltage causes the reversible trapping of the positive charge in
 the dielectric layer, without electrical degradation of the dielectric and dielectricsemiconductor
 interface. The capture cross-sections of the hole traps are around 10⁻¹⁸ and
 2 × 10⁻²⁰ cm²
 . The respective shift of the C–V curve correlates with a “plateau” at the
 capacitance corresponding to weak accumulation at the silicon interface.
