	abstract = {We use scanning tunneling spectroscopy to investigate the filled and empty electronic states of superconducting single-unit-cell FeSe deposited on\&nbsp;SrTiO3(001). We map the momentum-space band structure by combining quasiparticle interference imaging with decay length spectroscopy. In addition to quantifying the filled-state bands, we discover a\&nbsp;Γ-centered electron pocket 75\&nbsp;meV above the Fermi energy. Our density functional theory calculations show the orbital nature of empty states at\&nbsp;Γ\&nbsp;and explain how the Se height is a key tuning parameter of their energies, with broad implications for electronic properties.},
