XXI научно-техническая конференция с участием зарубежных специалистов "Вакуумная наука и техника"
The Collection is of interest to scientists and professionals working in the field of electronics and in sectors of the economy, where applicable, vacuum devices and equipment. They can also be useful for undergraduate and graduate students enrolled at the relevant specialties, in their scientific and educational activities.
Was regarded a possibility of using in the high-vacuum equipment the additional funds of pumping, placed in intra-cameral space. The operating mode and operating conditions of the research equipment determine a number of specific requirements to technical and operational parameters of the built in pumping devices and limit using for these purposes traditional means of pumping. The best indicators have pumps with not sprayed gas absorbers.
The photoemission of excess charge carriers into high-ohmic gallium arsenide was investigated. It was revealed, that the illumination even small local sample areas located far from contacts, influences both on contacts transition resistance and on volume conductivity of the crystal. On Suite-voltage dependencies there is a linear plot, angular coefficient which is directly proportional to the diameter of the illuminated surface. The model qualitatively explain the experimental results.
