We explored the influence of the pyramid field effect on the electrical resistance of carbon materials. The research object was pyrolytic carbon obtained by precipitating the products of the pyrolysis of methane on a graphite liner at a temperature of ~2100C. Measurements were taken by the four-probe method on direct current under normal conditions. The size of the sheet was ~25×10×1mm; the distance between the potential contacts ~3mm. The measuring current had a density of ~1500mA/cm2. Before exposure in the pyramid the electrical resistance was measured at ~5–7μΩ (micro ohms)/m. After exposure in the pyramid for 24 hours resistance approximately doubled. Such changes are anomalous for pyrocarbon. Even neutron bombardment with at about 1019 neutrons/cm2 does not produce changes of more than 5%.
Over time the changes taking place in electrical resistance varied from +100% to -100% following a sine curve. Besides, we discovered a reduction in the electrical resistance of silicon of semiconductor purity from 105 Ω/cm2 to 104 Ω/cm2 and a loss of high temprature superconductivity in samples after exposure in the pyramid.
