| The behaviour of germanium on atomically clean niobium single crystal planes has been studied by probe-hole field emission microscopy as well as by means of the spectral analysis of field emission current fluctuations. Variations of average work function, surface diffusion activation energies, and slopes of the spectral density function with different coverages and substrate temperatures are measured. |
