The influence of the defects induced by fast-neutron irradiation on the rate of charge-carrier removal in nuclear-doped silicon
(p-Si < B, P>) and a test p-Si < B > sample is studied by measuring the Hall coefficient and resistivity at room temperature. It is shown that the rate
of removal of charge carriers in p-Si < B, P > is higher than that in p-Si < B>. A barrier model is developed to explain the observed effect. 相似文献

The mechanoelectric effects under weak electric polarization and elastic deformation of glass and marble samples are investigated.
The electric potentials of no relation to the piezoelectric effect are measured. The induced electric potential relaxation
is studied and the activation energy of this process is estimated. The induced potential relaxation mechanism is proposed.
The electric field potentials in the sample are measured by the contactless method with a specially constructed electrometer
of a high input voltage. 相似文献

The properties of the Earth’s solid crust have been studied on the assumption that this crust has a block structure. According to the rotation model, the motion of such a medium (geomedium) follows the angular momentum conservation law and can be described in the scope of the classical elasticity theory with a symmetric stress tensor. A geomedium motion is characterized by two types of rotation waves with shortand long-range actions. The first type includes slow solitons with velocities of 0 ≤ Vsol ≤ c0, max = 1–10 cm s–1; the second type, fast excitons with V0 ≤ Vex ≤ VS–VP. The exciton minimal velocity (V0 = 0) depends on the energy of the collective excitation of all seismically active belt blocks proportional to the Earth’s pole vibration frequency (the Chandler vibration frequency). The exciton maximal velocity depends on the velocities of S (VS ≈ 4 km s–1) and/or P (VP ≈ 8 km s–1) seismic (acoustic) waves. According to the rotation model, a geomedium is characterized by the property physically close to the corpuscular–wave interaction between blocks that compose this medium. The possible collective wave motion of geomedium blocks can be responsible for the geomedium rheidity property, i.e., a superplastic volume flow. A superplastic motion of a quantum fluid can be the physical analog of the geomedium rheid motion. 相似文献
