Seik et al. took a tungsten diselenide (WSe2) surface and then exposed it to the ultrafast light pulse. The electron emission was different at times. This happened because of the centrifugal barrier (repulsive force) that is related to the electron angular momentum. The observed results were- Ø Electrons having lower angular momentum gets released or … Continue reading “PHOTOEMISSION TO BE SLOWED DOWN BY ANGULAR MOMENTUM”
