Thermo-optic coefficient of gst
WebbIn this work, the thermo-optic coefficient (TOC) of the silicon-rich amorphous silicon carbide (a-SiC) thin film deposited by plasma-enhanced chemical vapor deposition (PECVD) was characterized. We found that the TOC of the film increases as its silicon content increases. A more than threefold improvement in the TOC was measured, … Webb9 dec. 2024 · the thermo-optic effect of these materials are very limited.
