“…Copper and indium atoms are least bound oned in the chalcopyrite molecule, which was the main component of massive electrodes [19]. Therefore, the linear section of the plasma radiation spectrum is mainly produced by separate spectral lines of copper and indium atoms and single-charged ions both for laser plasma formed in vacuum at the surface of the target made of this compound [20] and for gas discharge plasma on the basis of air, nitrogen, or argon for overstressed nanosecond discharge between copper electrodes under atmospheric pressure [21]. The radiation emission spectrum of the gaseous component, argon, did not manifest itself in this spectral interval.…”

Приведено оптичнi характеристики i параметри перенапруженого наносекундного розряду в аргонi мiж електродами з алюмiнiю i халькопiриту (СuInSe2) при p(Ar) = 13,3 і 101 кПа. Внаслiдок мiкровибухiв природних неоднорiдностей на робочих поверхнях електродiв в сильному електричному полi в плазму вносяться як пари алюмiнiю, так I пари халькопiриту, що створює передумови для синтезу за межами розряду тонких плiвок четверного халькопiриту – CuAlInSe2. Дослiджено iмпульси напруги i струму на розрядному промiжку величиною d = 1 · 10−3 м (розмiри наведено в системi СI), а також iмпульсний енергетичний внесок у плазму. Ретельно дослiджено спектри випромiнювання плазми, що дозволило встановити основнi продукти розпаду молекули халькопiриту та енергетичнi стани атомiв i однозарядних iонiв алюмiнiю, мiдi i iндiю, в яких вони утворюються в розрядi. Виявлено репернi спектральнi лiнiї атомiв I iонiв алюмiнiю, мiдi i iндiю, якi можуть бути використанi для контролю за процесом напилення тонких плiвок четверного халькопiриту. Методом числового моделювання параметрiв плазми перенапруженого наносекундного розряду на основi парiв алюмiнiю i халькопiриту, шляхом розв’язку кiнетичного рiвняння Больцмана для функцiї розподiлу електронiв за енергiями розраховано температуру i концентрацiю електронiв у розрядi, питомi втрати потужностi розряду на основнi електроннi процеси i константи швидкостi електронних процесiв в залежностi вiд величини параметра E/N (де E – напруженiсть електричного поля, N – загальна концентрацiя сумiшi парiв алюмiнiю та аргону).

“…Thin films composed of argon-silver sulfide plasma were fabricated using the technique outlined in [12,13]. By positioning a glass substrate approximately 2-3 cm away from the discharge center and operating at pulse frequencies ranging from 500 to 1000 Hz, homogeneous thin films were produced from electrode erosion products under the influence of a nanosecond discharge with overvoltage in heavy inert gases like argon.…”

The study explores the specifications of a nanosecond overvoltage discharge in argon occurring between electrodes crafted from a superionic conductor, silver sulfide (Ag2S). The discharge was initiated under argon pressures ranging from 13.3 to 101 kPa, with a 2 mm separation between the polycrystalline Ag2S electrodes. Electrode material degradation within the discharge, alongside the introduction of Ag2S vapor into the interelectrode region, stemmed from microexplosions triggered by inherent surface irregularities on the electrodes. This discharge configuration holds potential as a plasma-chemical reactor for synthesizing thin films predicated on silver sulfide. Additionally, the study presents findings from analyzing Raman scattering spectra of laser radiation interacting with films synthesized from the Ag2S compound.

“…the study of the cross-sectional surface of nanostructures and a glass substrate (in the Overstressed Nanosecond Discharge in the Gases at Atmospheric Pressure direction perpendicular to the substrate) has not been carried out, but, based on the known conditions for the synthesis of such nanostructures using a magnetron discharge, it is possible to assume that these can be nanowhiskers of copper or zinc oxides. At elevated air pressures and the energy contribution to the plasma (when using magnetrons, nanosecond discharges in liquid or air), the formation of nanodispersion or nanostructures of complex-shaped transition metal oxides is recorded [51][52][53][54][55][56][57][58][59][60][61][68][69][70][71].…”
