STUDY OF AGRO-PRODUCTIVE FEATURE FEATURES OF SOIL COVER OF GANJA-KAZAKH REGION OF AZERBAIJAN

In the article, the object of study of the Ganja-Gazakh steppe is widely distributed in the following areas: Mountain-forest brown soils washed from carbonates (Haplic Castanozems). Mountain-brown soils (Kastonozems) from the forest, washed from carbonates. Under the forest, carbonate mountain-brown soils (Kastonozems). Wild mountain-forest brown soils (Mollic Leptosols Eutric). Carbonate mountain-black soils (Chernozems, 1350 m). Dark mountain gray-brown soils (Castanozems). Ordinary mountain gray-brown soils (Castanozems). Light mountain gray-brown soils (Castanozems). Dark gray-brown soils (Haplic Castanozems Chromic). Common gray-brown soils (Haplic Castanozems Chromic). Dark gray-brown, Light gray-brown soils (Castanozems). Wetland-meadow soils (Gleysols). Field-soil-erosion researches were carried out, numerous sections were made in these soils and samples were taken from different genetic layers and laboratory analyzes were carried out, their granulometric composition, agro-chemical and water-physical properties were studied and studied. solid phase density, hygroscopic moisture, soil swelling ability, its compaction capacity, pH.In water suspension, the sum of absorbed bases, m.eq., the sum of absorbed bases, Na%, Carbonate content, total nitrogen and humus content were determined and their erosion limits were determined.

Transport Properties of B-, P-Doped and Undoped 50 kHz PECVD Microcrystalline Silicon

Undoped 500 nm-thick silicon layers with a crystalline fraction around 95% and an average grain size of 20 nm have been deposited at 350°C by 50 kHz triode PECVD in a H2/SiH4 mixture, in the presence of a magnetic field. Their room temperature (rt) dc conductivity μrt is 0.03 Δ−1cm−1 for a Hall mobility of 0.8 cm 2V−1s−1.The study by SIMS, infrared absorption, grazing angle x-ray diffraction and Raman scattering spectroscopies of the doped samples shows how the crystalline fraction and the grain size drop as the B2H6/SiH4 and PH3/SiH4 volumic ratios increase from 10 ppm to 1%.The rt dc conductivity reaches 2 Δ−1 cm−1 (Hall mobility: 15 cm2V−ls−1) for a solid phase density of 1019 cm−3 boron atoms, and 30 Δ−1cm−1 (Hall mobility: 55 cm2V−ls−1) at the maximum P incorporation of 8 × 1020cm−3.
