Abstract
Ion irradiation with Xe+ has been utilized to produce electrical condu ctivity in PMMA, as measured using a four-point in-line probe. Inciden t ion beam energy and current density have been varied to investigate their effect on electrical conductivity and optical absorbance of the samples after irradiation. Results support the premise that selection of beam parameters that maximize the ratio of energy transfer-producin g displacements to energy transfer-producing ionization maximizes the ratio of induced conductivity to induced absorbance in the irradiated samples. Conductivity versus ion dose has also been shown to be well e stimated using a damage trail model. (C) 1994 John Wiley and Sons, Inc .
