## Title

- title: Nano-Raman Spectroscopy Figure of Merit and Chemical Analysis of Contaminations
    in Single-Layer MoSe<sub>2</sub>
  title_type: original
  lang: en

## Description

- description: Contaminations in the formation of two-dimensional heterostructures
    can hinder or generate desired properties. Recent advancements have highlighted
    the potential of tipenhanced Raman spectroscopy (TERS) for studying materials
    in the 2D semiconductor class. In this work, we investigate the influence of 50-200nm
    sized nanoprotuberances within a monolayer of MoSe2 deposited on hBN using nano-Raman
    spectroscopy, establishing correlations between the presence of localized contaminations
    and the observed hyperspectral variations. A figure of merit is established for
    the identification of surface contaminations, based on MoSe2 peaks ratio. Notably,
    new spectral peaks were identified, which are associated with the presence of
    nanoprotuberances and may indicate contamination, oxidation, or trapped gases
    within them.
