O'ZBEKCHA

PbSe polikristall plyonkalarining elektr o‘tkazuvchanligi va tenzosezgirlik xossalariga texnologik parametrlarning ta’siri o‘rganildi. Taglik harorati, cho‘ktirish holati va plyonka qalinligining zaryad tashuvchilar ko‘chishiga ta’siri tahlil qilindi. Ushbu parametrlarning o‘zgarishi elektr o‘tkazuv-chanlikka ta’sir qilishi hamda p-turdan n-tur o‘tkazuvchanlikka o‘tishni yuzaga keltirishi aniqlandi. Kuza-tilgan holatlar tarkibiy bir jinslilikning buzilishi, donalar chegarasidagi potensial to‘siqlar va zaryad ta-shuvchilarning qayta taqsimlanishi bilan izohlanadi. Optimal texnologik sharoitlar PbSe plyonkalarining elektr o‘tkazuvchanligi va tenzosezgirligini oshirish imkonini beradi.

Kalit so'zlar: PbSe, polikristall plyonka, elektr o‘tkazuvchanlik, tenzosezgirlik, pyezorezistiv effekt, taglik harorati, plyonka qalinligi, o‘tkazuvchanlik turi inversiyasi, texnologik omillar.

Исследовано влияние технологических параметров на электропроводность и тензочувствительные свойства поликристаллических пленок PbSe. Проанализировано влияние температуры подложки, положения осаждения и толщины пленки на перенос носителей заряда. Установлено, что изменение этих параметров влияет на электропроводность и может вызывать переход от p-типа к n-типу проводимости. Наблюдаемое поведение связано с неоднородностью состава, потенциальными барьерами на границах зерен и перераспределением носителей заряда. Оптимальные технологические условия обеспечивают повышение электропроводности и тензо-чувствительности пленок PbSe.

Ключевые слова: PbSe, поликристаллические пленки, электропроводность, тензочувстви-тельность, пьезорезистивный эффект, температура подложки, толщина пленки, инверсия типа проводимости, технологические факторы
ENGLISH

The influence of technological parameters on the electrical conductivity and strain-sensitive properties of polycrystalline PbSe films was investigated. The effects of substrate temperature, deposition position, and film thickness on charge transport were analyzed. Changes in these parameters were found to affect electrical conductivity and may cause a transition from p-type to n-type conductivity. This behavior is attributed to compositional inhomogeneity, grain-boundary barriers, and charge-carrier redistribution. Optimal technological conditions provide enhanced electrical conductivity and strain sensitivity of PbSe films.

Keywords: PbSe, polycrystalline films, electrical conductivity, strain sensitivity, piezoresistive effect, substrate temperature, film thickness, conductivity-type inversion, technological factors.
