Abstract

fetched live from OpenAlex

The dielectric properties have been determined for stoichiometric amorphous hydrogenated silicon carbide (a-SiC:H) films grown by means of the plasma-enhanced chemical vapor deposition (PECVD) technique. The dielectric constant, dielectric loss, breakdown voltage, and current–voltage (I–V) characteristics of the a-SiC:H PECVD films were systematically determined for various film thicknesses in the 90–1400 nm range. The PECVD a-SiC:H films exhibit not only a dielectric constant as high as 14 but also relatively high breakdown field values around 3 MV/cm. The dielectric constant of the a-SiC:H films was found to remain almost constant over all the investigated frequency range of 1 kHz to 13 MHz, while it decreases as the film thickness is diminished. The analysis of the I–V characteristics of the a-SiC:H films has revealed the existence of two different conduction mechanisms depending on the applied voltages. While exhibiting an ohmic conduction in the low-field region (<0.05 MV/cm), the film conduction at high fields (>0.25 MV/cm) is dominated by the Poole–Frenkel effect. In the low-field region, the conductivity of the a-SiC:H films was found to decrease exponentially from 10−10 S/cm to about 10−12 S/cm as the film thickness is increased from 90 to 1400 nm. At high fields, a thermal breakdown of the a-SiC:H films occurred at about 3 MV/cm as a consequence of thermal instabilities induced by Joule heating. The excellent dielectric properties of the PECVD a-SiC:H films are seen to be a consequence of their high density and low defect concentration.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.
