能量分布弛豫谱技术界面陷阱MOS结构According to the definition of interface traps,a new application of relaxation spectral technique to sub-threshold swing shift and sub-threshold gate voltage shift is proposed to extract interface trap density in 1.9nm MOSFET.And thus the energy distribution of ...
We compare the effect of hydrogen, nitrogen, and phosphorus passivation on total near interface trap density and mobility of 4H(0001)-SiC/SiO_2 structure. The results show that nitrogen and phosphorus passivation decrease total near interface trap density by pushing the energy levels of interface ...
We demonstrate an accurate measurement of the interface trap density and the stress-induced dielectric charge density in Si/high-/spl kappa/ gate dielectric stacks of metal-oxide-semiconductor field-effect transistors (MOSFETs) using the direct-current current-voltage (DCIV) technique. The capture cr...

Increasing the donorlike trap density decreases the threshold voltage in capped devices, whereas it leaves it unchanged in uncapped ones. As a result, donorlike interface traps can explain the threshold-voltage difference observed in MOSFETs with and without the cap.[ABSTRACT FROM PUBLISHER] 展开 ...
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 ...
A method to characterize near-interface oxide trap density in SiC MOS capacitors using transient capacitance measurements was investigated, taking account of the distribution of de-trapping time of traps of various locations in oxide. The measurements at room and low temperatures enables us evaluate th...
The Ba-modified MOSFETs show a slight decrease in mobility with heating to 150°C, as expected when mobility is not interface-trap-limited, but phonon-scattering-limited. With a Ba interface layer, the interface state density 0.25eV below the conduction band is 3×1011cm2eV1, lower than ...
