The Manufacture of Inverse Photoemission Spectroscopy

Abstract

We manufactured an equipment for inverse photoemission spectroscopy (IPES) which directly gives the information on unfilled density of state of a surface. We estimated the calculated resolution of this equipment at 1.1 eV, whereas experimental resolution of about 1.3 eV was obtained from a Au spectrum. From this value, manufactured equipment seems to approximately satisfy the condition of design. Therefore, manufactured IPES are considered to be useful method for the investigation of the surface.
