We are able to achieve current pinch-off using independent split gates and observe current steps suggesting possible carrier confinement. We also investigated the impact of gate geometry and used electrostatic potential simulations to explain the observed device physics. © 2019, The Author(s). | Source Title: | Scientific Reports | URI: | https://scholarbank.nus.edu.sg/handle/10635/209513 | ISSN: | 2045-2322 | DOI: | 10.1038/s41598-019-45392-9 | Rights: | Attribution 4.0 International |
