Inverse photoemission studies on InSe conduction band

We reporl on inverse photoemission studies ([PESi obtained on freshly pealed InSe. The spectra have been taken with a Geiger-MUIler-type detector and a resulting resolution of ahoul 0.4 eV. The electron beam was not collimated thus leading to angle-integrated spectra. The data shaw peaks at 2,3, 5A and a broad fcatnre at 7.5 eV above E F. The results are compared with previous theorelical calculations.
