Abstract
Film samples of the polymer poly-para phenylene-benzohis-thiazole (PBT) are implanted at room temperature with multiple implants of 1 and Kr ions up to total fluences of $10^{16}$ and $10^{17}$ ions/$cm^{2}$. Ion energies and corresponding doses are determined using an analytical version of the TRIM code to achieve a uniform implant distribution to a depth of approximately $0.1\mu $m. The microwave conductivity of the implanted samples is measured using a microwave network analyzer and a cavity-perturbation technique. The latter climinates the need to evaluate the depolarization factor which has a large uncertainty for arbitrarily shaped samples. A prototype design of a millimeter wave (FET) will be discussed. Results have been analyzed in terms of an energy-dependent hopping model.
