Our recent study “Direct Imaging of Electron Transfer and Its Influence on Superconducting Pairing at FeSe/SrTiO3 Interface” has been accepted by Science Advances. It provides most straightforward evidence up so far of the charge transfer process from STO to mysterious FeSe superconductors using the unique low-temperature atomic-resolution Electron Energy Loss Spectroscopy (EELS), and also provides conclusive evidence of interfacial atomic structures. Congratulations!
