Abstract
POLYMERS may be rendered semiconducting by heating to form graphitic structures1. Such nonspecific treatment results in a drastic deterioration of physical properties of the polymer and a change in form of the samples. We have found that ultra-violet light irradiation of chlorinated high polymers transforms them into semiconductors. This treatment has advantages over the pyrolysis method in that : (a) by selective choice of ultra-violet wave-lengths specific chemical reactions are produced ; (b) the reactions may be confined to specified areas. In fact, we have found that at the border of irradiated regions unique p–n junctions are produced.
