摘要

角分辨光电发射是动量分辨电子结构的直接探针，被证明在研究具有新电子性质的体相晶体方面具有重要影响。由于最近的技术进步，这项技术现在可以首次应用于研究通过堆叠二维晶体构建的范德华异质结构。在这篇文章中，我们将介绍二维材料角度分辨光电发射测量的最新技术，并回顾这个仍然年轻的领域。我们将特别关注与传输和光学实验中使用的器件类似的器件，包括魔角扭曲双层石墨烯的最新进展，以及栅极可调谐器件的工作特性。

Electronic structure of 2D van der Waals crystals and heterostructures investigated by spatially- and angle-resolved photoemission

Angle-resolved photoemission is a direct probe of the momentum-resolved electronic structure and proved influential in the study of bulk crystals with novel electronic properties. Thanks to recent technical advances, this technique can now be applied for the first time for the study of van der Waals heterostructures built by stacking two-dimensional crystals. In this article we will present the current state of the art in angleresolved photoemission measurements on two-dimensional materials and review this still young field. We will focus in particular on devices similar to those used in transport and optics experiments, including the latest developments on magic-angle twisted bilayer graphene and on the in-operando characterization of gate tunable devices.

期刊介绍： The Comptes Rendus - Physique are an open acess and peer-reviewed electronic scientific journal publishing original research article. It is one of seven journals published by the Académie des sciences. Its objective is to enable researchers to quickly share their work with the international scientific community. The Comptes Rendus - Physique also publish journal articles, thematic issues and articles on the history of the Académie des sciences and its current scientific activity. From 2020 onwards, the journal''s policy is based on a diamond open access model: no fees are charged to authors to publish or to readers to access articles. Thus, articles are accessible immediately, free of charge and permanently after publication. The Comptes Rendus - Physique (8 issues per year) cover all fields of physics and astrophysics and propose dossiers. Thanks to this formula, readers of physics and astrophysics will find, in each issue, the presentation of a subject in particularly rapid development. The authors are chosen from among the most active researchers in the field and each file is coordinated by a guest editor, ensuring that the most recent and significant results are taken into account. In order to preserve the historical purpose of the Comptes Rendus, these issues also leave room for the usual notes and clarifications. The articles are written mainly in English.
