Start by defining or describing (one paragraph) van der Waals heterostructure

Learning Goal: I’m working on a science report and need support to help me learn.

Start by defining or describing (one paragraph) van der Waals heterostructure, which is a structure made by vertically stacking layers of different materials (in this case 2D materials) such that the layers are held together by van der Waals forces and the meaning or thermoelectric properties(seebeck, peltier, power factor, figure of merit(ZT)). Go to this link https://scholar.google.com/scholar?q=%22graphene%2… where you will find relevant articles. For this work use only articles from 2021 to date.. write a paragraph for each article describing the method(experimental or computational) used and major observations made. You should describe at least 20 articles, so I expect at least 20 paragraphs each explaining research work from a specific (one) article. The articles must be published journal articles found in the google scholar link. Use English to answer this question. These links could be helpful in accessing the articles https://www.google.com/search?q=sc+hub+se&ei=qz1dY… . Kindly stick to the two materials only, graphene and BN verticle heterostructures.

Give the reference after each paragraph, Organize the work in this format:

Paragraph 1

Reference 1

paragraph 2

Reference 2
