Angle-resolved photoemission spectroscopy (ARPES) from VSe2 ranging from a single layer to the bulk reveals the evolution of the electronic structure including the Fermi surface contours and the CDW gap. At a thickness of two layers, the ARPES maps are already nearly bulklike, but the","authors_text":"A.-V. Fedorov, H. T. Zhang, M. Y. Chou, P. Chen, Q. Gao, R.-Y. Liu, T.-C. Chiang, Y.-H.
