The Effect Of Annealing On The Crystal Structure Of The Silicon Surface Doped With Nickel Ions

Egamberdiev B.E, Mamirov Kh.H — Sun, 06 Apr 2025 00:00:00 +0000

The paper presents the results of a study of the distribution profiles of implanted nickel atoms in silicon as a function of the radiation dose and the annealing temperature using the Rutherford backscattering spectrometry technique (RBS). The effects of thermal annealing on the distribution of nickel and in particular oxygen are studied. It has been proven that under certain conditions of heat treatment and radiation doses, the so-called epitaxial silicides are formed on the surface of a single crystal, which can play the role of conductive layers or metallic coatings. The possibility of using the RBS technique for analyzing both the concentration distribution of doping impurities and the interaction of impurities is argued.

The moistening of raw cotton and cotton fiber is a critical stage in the textile production process, significantly influencing the quality of the final product. However, achieving optimal moisture content presents numerous challenges. One of the primary problems is the uneven distribution of moisture during processing, which can lead to variations in fiber strength and quality. The inappropriate application of water or humidification methods often causes fiber shrinkage, reduced durability, and increased contamination. Furthermore, the control of temperature and humidity plays a vital role in preventing over-drying or excessive moisture retention, both of which can negatively affect the spinning and handling properties of cotton fibers. Technological limitations, coupled with the complexity of monitoring moisture levels accurately, result in inefficiencies in the cotton processing industry. Research has also shown that improper moisture regulation can lead to decreased efficiency in machinery, increased energy consumption, and a higher likelihood of fiber damage during transportation and storage. Therefore, addressing these issues requires advancements in moisture control technologies and the development of standardized procedures to ensure consistent and high-quality cotton fiber production
