Recently, two-dimensional transition metal dichalcogenides have intrigued much attention due to their promising applications in optoelectronics. The electrostatic property investigation of WSe2 nanostructures is essential for device application. Here, the interlayer screening effects of WSe2 nanoplates with different thicknesses were investigated by measuring surface potential employing Kelvin probe force microscopy. Simultaneously, charges can be injected into WSe2 nanoplate by means of conducting atomic force microscopy to tune the electrostatic properties of WSe2 nanostructures. Our experimental results have some important implications for improving performance of WSe2-based optoelectronic devices through interface or surface engineering. © 2016 AIP Publishing LLC.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
