Researchers find electron current direction in photondrag effect is dependent on surrounding

first_imgA team of researchers at the U.S. National Institute for Standards and Technology has found that electron current flow direction produced by the photon-drag effect is dependent on the environment in which a metal is sitting. In their paper published in Physical Review Letters, the group describes experiments they conducted with polarized light striking a gold film and what they learned.
