- Abstract:
-
Synthetic 2D crystal films growth by chemical vapour deposition are typically polycrystalline and determining grain size within domains and continuous films is crucial for determining their structure. Here we show that grain boundaries in the 2D transition metal dichalcogenide WS2, grown by CVD can be preferentially oxidized by controlled heating in air. Under our developed conditions, the bulk WS2 remains relatively unaffected, whilst preferential degradation at the grain boundaries causes a...

Access Document
Why is the content I wish to access not available via ORA?
Bibliographic data (the information relating to research outputs) and full-text items (e.g. articles, theses, reports, etc.) arrive in ORA from several different sources. Unfortunately we are not able to make available the full-text for every research output.
Please contact the ORA team (
) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
