An apparatus for the low-energy inverse photoemission spectroscopy is described. In this technique, low energy electron having kinetic energy below 4 eV is incident to the sample and detect the emitted photons in the near ultraviolet range (below 5 eV, longer than 250 nm) to investigate the unoccupied states of the solid materials. Compared with the prototype apparatus reported previously [H. Yoshida, Chem. Phys. Lett. 539-540, 180-185 (2012)], the collection efficiency of photons is improved by a factor of four and practically any conductive substrates can be used. The overall resolution is 0.27 eV.
描述了一种用于低能逆光电子能谱的装置。在该技术中，动能低于4 eV的低能电子入射到样品上，并检测近紫外范围内（低于5 eV，大于250 nm）发射的光子，以研究固体材料的未占据态。与先前报道的原型装置[H. Yoshida, Chem. Phys. Lett. 539 - 540, 180 - 185 (2012)]相比，光子的收集效率提高了四倍，并且实际上可以使用任何导电衬底。整体分辨率为0.27 eV。
