1. Carbon Nanotube Worksheet

   01 Apr 2021 | | Contributor(s):: Tanya Faltens

   This worksheet is made to be used with the CNT Bands tool in nanoHUB.  (https://nanohub.org/tools/cntbands-ext) Students identify armchair, zig-zag and chiral CNTs based on CNT geometry. Students identify semiconducting and metallic CNTs based on their energy band diagrams.  ...

2. Why does the electric field never change its sign?

   Q&A|Closed | Responses: 3

   Hello

   I noticed while performing simulations, that the electric field does not change its sign when a DC bias greater than the built-in voltage is applied. One can...
