the work function of the LEEM instrument i.e., of the electron emitter cathode is determined.Using this calibration procedure, we nd =4.75–4.91 V for the quasicrystal surface, where the rangeof values is due to the range of literature values for the cleanelemental surfaces that served as benchmarks and also par-tially due to the consistency in the work function determina-tion of the LEEM instrument. The literature work functions
