Ambient Pressure Photoemission Spectroscopy With Nitrogen Environment
The APS04-N2-RH incorporates a tuneable deep ultra-violet (UV) source outputting 3.4 - 7.0 eV, for absolute work function and highest occupied molecular orbital (HOMO) measurements, a surface photovoltage spectroscopy (SPS) module outputting 400 - 1000 nm for Voc and Eg measurements, together with a 50 x 50 mm scanning area for planar relative work function measurements (Fermi level).
