Abstract

We explore the use of Si₃N₄/Si substrates as a substitute of the standard SiO₂/Si substrates employed nowadays to fabricate nanodevices based on 2D materials. We systematically study the visibility of several 2D semiconducting materials that are attracting a great deal of interest in nanoelectronics and optoelectronics: MoS₂, MoSe₂, WSe₂ and black-phosphorus. We find that the use of Si₃N₄/Si substrates provides an increase of the optical contrast up to a 50%–100% and also the maximum contrast shifts towards wavelength values optimal for human eye detection, making optical identification of 2D semiconductors easier.
