Time resolved two-colour VUV-IR photoemission in wide band gap dielectrics
We have measured the relaxation of photo‐excited carriers in different wide band gap dielectrics by using time resolved two‐colour photoemission. Electrons are excited by an ultra‐short pulse of VUV photons directly in the conduction band. They are then are re‐excited by an IR probe pulse. The evolu...

Summary: | We have measured the relaxation of photo‐excited carriers in different wide band gap dielectrics by using time resolved two‐colour photoemission. Electrons are excited by an ultra‐short pulse of VUV photons directly in the conduction band. They are then are re‐excited by an IR probe pulse. The evolution of the photoemission spectra as a function of the pump‐probe delay gives direct information on the relaxation of the population of excited electron. (© 2005 WILEY‐VCH Verlag GmbH & Co.
