The appearance of van der Waals (vdW) electronic materials has motivated intensive studies of novel atomic layer electronic and photonic devices based on the heterostructures formed between dissimilar vdW materials. To understand the unusual properties and new phenomena of such heterostructures, the study of chemical and electronic structures of the vdW heterojunctions are essential.

In this presentation, I will present some of our recent results regarding the studies of vdW heterostructures by utilizing synchrotron radiation based soft X-ray photoemission spectromicroscopy, and some of the future perspective will be discussed.
