Methods of reducing the photoelectron yield and / or secondary electron yield of ceramic surfaces, corresponding devices and products

摘要

A method of reducing the photoelectronic yield (PEY) and / or the secondary electron yield (SEY) of a ceramic surface comprises applying a laser (4) to the surface of the target (10) to produce an array of periodic structures on the surface / RTI applying a pulsed laser radiation comprising a series of laser pulses emitted by the laser.
