a clean nickel surface is exposed to light of wavelength 235nm. what is the maximum speed of the photoelectrons emmited from This surface?

Expert Solution

Work function of Nickel is 5.01 eV. According to the photoelectric effect law maximum kinetic energy of electron is the excess amount of energy presesnt in the light photon over the work function.For a photon . where E is the energy of light photon h=planks constant e=electron charge c= speed of light . Energy of given photon . Work function .

where K.E. is kinetic energy of photoelectron.

1. A coupon of very pure Gold and highly clean surface is exposed to an Argon Fluoride (ArF) excimer laser beam of wavelength 193.4±0.2 nm inside an ESCA (Electron Spectroscopy for Chemical Analysis) ultrahigh vacuum spectrometer. The coupon surface faces the entrance aperture of a hemispherical electrostatic energy analyzer and detector. The coupon and the analyzer entrance aperture are electrically connected together at ground potential (zero Volts). A fraction of the photo-emitted electrons enters the analyzer and their energy distribution...
