Using advanced sample engineering we performed simultaneous measurements of interlayer tunneling characteristics and in situ monitoring of temperature in Bi(2)Sr(2)CaCu(2)O(8 + delta) (Bi-2212) mesas. Together with a systematic study of size dependence of interlayer tunneling, this allowed unambiguous discrimination between artifacts of self-heating and gaps in the electronic spectra of Bi-2212. Such a confident spectroscopic information, which is not affected by self-heating or surface deterioration, was obtained for the first time for a high-T(c) superconductor. We also derived general expressions and formulated main principles of self-heating valid for a large variety of materials. 相似文献

A theoretical analysis is performed herein of the spectrum sensitivity of a solar cell with a metal-tunnel dielectric-semiconductor structure on the properties of the interfacial boundaries and conditions for maximal collection of charge by the photocarriers are determined. The photosensitivity of structures with different tunnel-dielectric thickness is measured experimentally in a broad spectrum range. Comparison of the computed and experimental dependences permitted proving the influence of departure of the majority charge carriers in the metal on the photosensitivity in the shortwave spectrum band and also determining certain contact parameters governing the structure photosensitivity, and therefore, the efficiency of the solar cells.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 30–35, November, 1990. 相似文献

A model is considered for the interaction with plasma of an “optical membrane” formed by bichromatic intersecting laser beams.
This model is used to describe a number of effects resulting from the mechanical action of light on resonant ions in the plasma.

(2S,4S)-4-Arylamino-2-carboxy-5-pyrrolidones were prepared by hydrolysis of dimethyl (2S,4S)-4-arylamino-N-phthaloylglutamates. The protonation constants of the arylamino group in the synthesized compounds were determined. The pyrrolidone ring is stable in acidic or neutral solutions. The relative stability of the pyrrolidone ring in alkaline solutions was studied by IR spectroscopy.Translated fromIzvestiya Akademii Nauk.
