“…Photoelectron emissions from particles occur when the photon energy is higher than the work function of the particle surface. Cardona and Ley (1978) defined the probability, Y, of the emission of an electron from a particle as a function of the photon energy (h · ν) and threshold in the following Equation [1]:…”

The primary purpose of this study is to measure the size-and composition-dependent responses of aerosol surface instruments designed to measure surface area related properties. The secondary purpose of this study is to investigate the difference in charging rate between singlets (NaCl particles) and agglomerates (diesel particles) by using diffusion chargers. Agglomerates (diesel particles at engine load 75%) acquire more charge than singlets (NaCl particles) by 15 and 17% for LQ1-DC and EAD, respectively.

“…Research on photwathode materials has a venerable tradition, dating back to the optimization of photomultipliers earlier this century [Sommer, 1968;Cardona and Ley, 1978]. The operating characteristics of a laser driven electron gun are, however, very different from the requirements of photomultipliers, motivating a renewal search for photocathode materials.…”

“…If the shortest electron pulses are desired it is important to minimize this width, because variations in the electron energies cause a temporal broadening of the pulse at the target. Classical work on photocathodes suggests that a laser photon energy close to the work function of the material would generate the smallest energy width [Sommer, 1968;Cardona and Ley, 1978]. However, recent work by a number of researchers in the field has convincingly demonstrated that at the large peak intensities of the ultrashort laser systems employed for electron guns the photoemission occurs via a multiphoton process [Schmuttenmaer et.…”

“…The electronic structure of PrOs 4 Sb 12 could be investigated using optical measurements and photoemission spectroscopy (PES). PES has been established as one of the most important methods to study the electronic structure of solids [11,12]. Other forms of photoemission spectroscopy used to study the electronic structure of solids includes X-ray photoelectron spectroscopy (XPS), electron spectroscopy for chemical analysis (ESCA), inverse photoemission spectroscopy (IPES) and electron energy loss spectroscopy (EELS).…”

Abstract. Here we report the electronic structure of praseodymium filled skutterudite compound PrOs 4 Sb 12 . The theoretical photoemission spectrum (PES) at ћω = 21.2 eV shows four distinct structures peaking at about -0.2, -7.7, -13.7 and -18.2 eV. But on increasing the photon energy to 40.8 eV, the peak at -0.2 eV becomes a prominent or pronounced peak, the peak at -7.7 eV decreases in intensity, the peak at -13.7 eV increases intensity, the peak at -18.2 eV reduces in intensity and another peak emerges. These structures are interpreted to be associated with the density-of-states features on the basis of the results of band structure calculation. Hence, the peak at -0.2 eV arises from the symmetry point P at -11.61 eV, the peak at -7.7 eV comes from the symmetry point P at -11.62 eV, the peak at -13.7 eV arises from the symmetry point P at -11.88 eV and the peak at -18.2 eV arises from the symmetry point P at -11.88 eV. The PES energy level difference for PrOs 4 Sb 12 fell within the range -0.5 to -7.5 eV indicating that it can be used in designing electronic devices. The energies of specific electronic states in the band structure of PrOs 4 Sb 12 showed that it could be used for the development of solid-state devices.
