Surface Photoeffect in Small Spheres



David R. Penn, R W. Rendell


A new method is developed to calculate the photoabsorption and photoyield of small spheres. Numerical results are presented for the case of free-electron spheres for photon energies below the plasmon energies. It is found that the excitation of electron-hole pairs due to the presence of the surface results in enhancements in photabsorption and photoyields that are typically 10-102 r elative to the classical results, which only include the excitation of transverse modes. Futhermore, enchancements of the order 10-102 are found in the photoyield of small spheres relative to plane surfaces. These results are consistent with recent experimental results on a number of non-free-electron materials.
