## Description

- description: We investigate the electronic properties of a graphene and α-ruthenium
    trichloride (α-RuCl3) heterostructure, using a combination of experimental and
    theoretical techniques. α-RuCl3 is a Mott insulator and a Kitaev material, and
    its combination with graphene has gained increasing attention due to its potential
    applicability in novel electronic and optoelectronic devices. By using a combination
    of spatially resolved photoemission spectroscopy, low energy electron microscopy,
    and density functional theory (DFT) calculations we are able to provide a first
    direct visualization of the massive charge transfer from graphene to α-RuCl3,
    which can modify the electronic properties of both materials, leading to novel
    electronic phenomena at their interface. The electronic band structure is compared
    to DFT calculations that confirm the occurrence of a Mott transition for α-RuCl3.
    Finally, a measurement of spatially resolved work function allows for a direct
    estimate of the interface dipole between graphene and α-RuCl3. The strong coupling
    between graphene and α-RuCl3 could lead to new ways of manipulating electronic
    properties of two-dimensional lateral heterojunction. Understanding the electronic
    properties of this structure is pivotal for designing next generation low-power
    opto-electronics devices.
