Laser-induced asymmetric faceting and growth of a nano-protrusion on a tungsten tip
Irradiation of a sharp tungsten tip by a femtosecond laser and exposed to a strong DC electric field led to reproducible surface modifications. By a combination of field emission microscopy and scanning electron microscopy, we observed asymmetr...
