(a) STM image of 1-UC FeSe film partially covered by the (1-UC & 2-UC) FeTe protection layer on conductive STO substrate. (b) STM image of the 1-UC FeSe film with some parts of the STO surface exposed. (c) The typical d I /d V spectra taken on the 1st-UC FeTe, the 2nd-UC FeTe, and the 1-UC FeSe films. (d) The typical d I /d V spectra taken on 1-UC FeSe film and exposed STO surface.^{[ 23 ]}
