We present an effective solution to a very difficult issue - namely interface trap density, Dit, spectra measurements on silicon PV dielectrics that exhibit large dielectric leakage. To achieve that goal, a noncontact, preparation-free corona C-V technique originally developed for silicon ...
aThe lowered value of boat-in temperature allows avoiding tearing-off defects on the wafers and reducing the amount of particle contaminants on the wafer. The boat-out temperature greater than the lowered value of boat-in temperature, allows avoiding degrading the trap interface density (Dit) of ...
5 illustrates the profile of interface trap density (DIT) versus energy level near the conduction band edge of the bandgap at the SiO2/SiC interface for several annealing conditions. DIT may be measured using any technique known to those of skill in the art. In this case, the results were ...
The minimum interface trap density Dit of 5×10eVcm near midgap is realized with a Si interlayer of 10 A. The hysteresis and frequency dispersion of the GaAs MIS capacitor were lower than 50 mV, and some of them as low as 30 mV under a field swing of about ±l·3MVcm. Ex-situ ...
The Si–SiO2 interface is also accompanied by non-negligible interfacial trap density Dit (units of surface states cm−2eV−1) distributed throughout the bandgap due to the break in the lattice structure at the interface. For a carefully treated {100} Si–SiO2 interface, typical mid gap ...

We show that the existence of sulfur vacancies at the MoS2-HfO2 interface is responsible for the generation of interface states with a density (Dit) reaching ~7.03 × 1011 cm−2 eV−1. This is evidenced by a deficit S:Mo ratio of ~1.96 using X-ray photoelectron spectroscopy...
