The measurement of very narrow high density plasma blocks of high ion
energy from targets irradiated with ps-TW laser pulses based on a new skin
depth interaction process is an ideal tool for application of ion
implantation in materials, especially of silicon, GaAs, or conducting
polymers, for micro-electronics as well as for low cost solar cells. A
further application is for ion sources in accelerators with most
specifications of many orders of magnitudes advances against classical ion
sources. We report on near band gap generation of defects by implantation
of ions as measured by optical absorption spectra. A further connection is
given for studying the particle beam transforming of n-type semiconductors
into p-type and vice versa as known from sub-threshold particle beams. The
advantage consists in the use of avoiding aggressive or rare chemical
materials when using the beam techniques for industrial applications.
