Coherent Field Emission Upon Ultrafast Laser Irradiation of the Tip Plasmon
Joonhee Lee, Shawn M. Perdue, Alejandro Rodriguez Perez +1
Irradiation of sharp silver tips with femtosecond laser pulses leads to photoassisted coherent field emission without a static field. We reconstruct the time profile of the emissio…

Photon momentum enabled light absorption in bulk silicon
Sergey S. Kharintsev, Aleksey I. Noskov, Elina I. Battalova +6
Photons do not carry sufficient momentum to induce indirect optical transitions in semiconducting materials such as silicon, necessitating the assistance of lattice phonons to cons…
