Changing the Properties of Semiconductors by Introducing Copper Doping Into Semiconductor Materials

This article extensively discusses the process of introducing copper (Cu) doping into semiconductor materials and its effect on the crystal lattice, electrical conductivity, energy band structure, and carrier concentration. The position of copper atoms in the silicon or germanium lattice during the doping process, their participation as donors or acceptors, and the shift of energy levels are analyzed based on experimental and theoretical sources. The changes in the physical, electrical, and structural properties of semiconductors as a result of doping with copper are considered on the example of real practice. The article is aimed at analyzing the role of copper in semiconductor manufacturing technologies, its advantages, and properties.
