Nanophotonic Ion Production from Silicon Microcolumn Arrays

Nanoantennas for ions: Silicon microcolumn arrays harvest light from a laser pulse to produce ions. The system behaves like a quasi-periodic antenna array with ion yields that show profound dependence on the plane of polarization and the angle of incidence of the laser beam.

Description
Summary:Nanoantennas for ions: Silicon microcolumn arrays harvest light from a laser pulse to produce ions. The system behaves like a quasi-periodic antenna array with ion yields that show profound dependence on the plane of polarization and the angle of incidence of the laser beam. Photonic ion sources promise to enable enhanced control of ion production on a micro- and nanometer scale and direct integration with miniaturized analytical devices.
