Abstract :
Oscillation phenomena accompanied by negative resistance were studied experimentally in oriented polypropylene (OPP). The negative resistance and current oscillation in OPP were measured according to changes in temperature and field. It is shown that the negative resistance can be interpreted based on J.F. Gibbons´ (1967) formulation. The mobility can be calculated from the oscillation current
