Your work is fairly good; I like that quality of papers you are citing. Where
are you from? A few things to check on:
➢ Kindly see the few comments I added for several answers.
➢ If a paper give several values for the same quantity just list all of
them and cite that paper.
➢ If several papers give values for the same quantity give all the
values and cite each.

What is the equilibrium distance (in nm) between a single layer of each of the following 2D
materials and a SiO2 substrate?
1. MoS2: 0.385 nm (Paul, S., et.al. (2022). Effect of the Substrate on MoS2 Monolayer
Morphology: An Integrated Computational and Experimental Study. Page 18841.
https://par.nsf.gov/servlets/purl/10392791 )
2. WSe2: 7.5 nm (Falin,A., et. al. (2021). Mechanical Properties of Atomically Thin
Tungsten Dichalcogenides: WS2, WSe2, and WTe2. Page: 2604.
https://pubs.acs.org/doi/epdf/10.1021/acsnano.0c07430 )
Is 7.5 nm equilibrium distance here really ?
3.
hBN: 0.33nm (Kim, J., et. al. (2023). Conformal Growth of Hexagonal Boron Nitride
on High-Aspect-Ratio Silicon-Based Nanotrenches. Page 2433.
https://pubs.acs.org/doi/epdf/10.1021/acs.chemmater.2c03568)
You did not understand the given 0.33nm is the hBN inter-layer distance but not the
distance between hBN and amorphous SiO2 substrates
4.
Phosporene: 0.273 nm (Shao, L., et. al. (2016). Interaction between phosphorene and the
surface of a substrate. Page 3. https://sci-hub.se/10.1088/2053-1591/3/2/025013 )

0.273 nm and 0.170 nm for Si-terminated SiO2 and O-terminated SiO2 respectively.
What is the adhesive energy (in J/m2) between each of the following 2D materials and a SiO2
substrate?
1.MoS2: 0.48248 J/m2

graphene and MoS2 to silicon and metal substrates. Page 8. Should be 7

“Furthermore, Liu et al estimated interlayer binding energies of various 2D materials by
combining first principles calculations and theoretical analyses [119]. It was found that graphene,
h-BN, MoS 2, graphyne, graphene oxide, and phosphorene have interlayer binding energies of
16.840, 16.189,26.992, 11.496, 28.610, and 21.851 meV Å−2 (correspondingto about 0.270,
0.259, 0.432, 0.184, 0.458, and 0.350 J m−2), respectively.” I don’t think you interprated this
correctly. This is interlayer binding energy, not binding energy of the 2D to the substrate.
What is the young’s modulus of a single layer of each of the following 2D materials?

This is a very good paper; it give several values, its good to give all of them and cite
the source.
